    Pressure-induced structural,electronic,and superconducting phase transitions in TaSe3

    李宇航周佩丁驰鲁清...
    98-105页
    查看更多>>摘要：TaSe3 has garnered significant research interests due to its unique quasi-one-dimensional crystal structure,which gives rise to distinctive properties.Using crystal structure search and first-principles calculations,we systematically investigated the pressure-induced structural and electronic phase transitions of quasi-one-dimensional TaSe3 up to 100 GPa.In addition to the ambient pressure phase(P21/m-Ⅰ),we identified three high-pressure phases:P21/m-Ⅱ,Pnma,and Pmma.For the P21/m-Ⅰ phase,the inclusion of spin-orbit coupling(SOC)results in significant SOC splitting and changes in the band inversion characteristics.Furthermore,band structure calculations for the three high-pressure phases indicate metallic natures,and the electron localization function suggests ionic bonding between Ta and Se atoms.Our electron-phonon coupling calculations reveal a superconducting critical temperature of approximately 6.4 K for the Pmma phase at 100 GPa.This study provides valuable insights into the high-pressure electronic behavior of quasi-one-dimensional TaSe3.

    Pit density reduction for AlN epilayers grown by molecular beam epitaxy using Al modulation method

    刘欢邵鹏飞陈松林陶涛...
    106-113页
    查看更多>>摘要：We have investigated homoepitaxy of AlN films grown by molecular beam epitaxy on AlN/sapphire templates by adopting both the continuous growth method and the Al modulation epitaxy(AME)growth method.The continuous growth method encounters significant challenges in controlling the growth mode.As the precise Al/N=1.0 ratio is difficult to achieve,either the excessive Al-rich or N-rich growth mode occurs.In contrast,by adopting the AME growth method,such a difficulty has been effectively overcome.By manipulating the supply time of the Al and nitrogen sources,we were able to produce AlN films with much improved surface morphology.The first step of the AME method,only supplying Al atoms,is important to wet the surface and the Al adatoms can act as a surfactant.Optimization of the initial Al supply time can effectively reduce the pit density on the grown AlN surface.The pits density dropped from 12 pits/μm2 to 1 pit/μm2 and the surface roughness reduced from 0.72 nm to 0.3 nm in a 2 × 2 μm2 area for the AME AlN film homoepitaxially grown on an AlN template.

    Regulating Anderson localization with structural defect disorder

    程谋阳陈浩翔陈基
    114-120页
    查看更多>>摘要：Localization due to disorder has been one of the most intriguing theoretical concepts that evolved in condensed matter physics.Here,we expand the theory of localization by considering two types of disorders at the same time,namely,the original Anderson's disorder and the structural defect disorder,which has been suggested to be a key component in recently discovered two-dimensional amorphous materials.While increasing the degree of both disorders could induce localization of wavefunction in real space,we find that a small degree of structural defect disorder can significantly enhance the localiza-tion.As the degree of structural defect disorder increases,localized states quickly appear within the extended phase to enter a broad crossover region with mixed phases.We establish two-dimensional diagrams for the wavefunction localization and conductivity to highlight the interplay between the two types of disorders.Our theoretical model provides a comprehen-sive understanding of localization in two-dimensional amorphous materials and highlights the promising tunability of their transport properties.

    Role of self-assembled molecules'anchoring groups for surface defect passivation and dipole modulation in inverted perovskite solar cells

    王啸宇Muhammad Faizan周琨王新江...
    121-129页
    查看更多>>摘要：Inverted perovskite solar cells have gained prominence in industrial advancement due to their easy fabrication,low hysteresis effects,and high stability.Despite these advantages,their efficiency is currently limited by excessive defects and poor carrier transport at the perovskite-electrode interface,particularly at the buried interface between the perovskite and transparent conductive oxide(TCO).Recent efforts in the perovskite community have focused on designing novel self-assembled molecules(SAMs)to improve the quality of the buried interface.However,a notable gap remains in understanding the regulation of atomic-scale interfacial properties of SAMs between the perovskite and TCO interfaces.This understanding is crucial,particularly in terms of identifying chemically active anchoring groups.In this study,we used the star SAM([2-(9H-carbazol-9-yl)ethyl]phosphonic acid)as the base structure to investigate the defect passivation effects of eight common anchoring groups at the perovskite-TCO interface.Our findings indicate that the phosphonic and boric acid groups exhibit notable advantages.These groups fulfill three key criteria:they provide the greatest potential for defect passivation,exhibit stable adsorption with defects,and exert significant regulatory effects on interface dipoles.Ionized anchoring groups exhibit enhanced passivation capabilities for defect energy levels due to their superior Lewis base properties,which effectively neutralize local charges near defects.Among various defect types,iodine vacancies are the easiest to passivate,whereas iodine-substituted lead defects are the most challenging to passivate.Our study provides comprehensive theoretical insights and inspiration for the design of anchoring groups in SAMs,contributing to the ongoing development of more efficient inverted perovskite solar cells.

    Hot carrier cooling in lead halide perovskites probed by two-pulse photovoltage correlation spectroscopy

    黄玉清郭钞宇高蕾杜文娜...
    130-134页
    查看更多>>摘要：The next-generation hot-carrier solar cells,which can overcome the Shockley-Queisser limit by harvesting excess energy from hot carriers,are receiving increasing attention.Lead halide perovskite(LHP)materials are considered as promising candidates due to their exceptional photovoltaic properties,good stability and low cost.The cooling rate of hot carriers is a key parameter influencing the performance of hot-carrier solar cells.In this work,we successfully detected hot carrier dynamics in operando LHP devices using the two-pulse photovoltage correlation technique.To enhance the signal-to-noise ratio,we applied the delay-time modulation method instead of the traditional power modulation.This advancement allowed us to detect the intraband hot carrier cooling time for the organic LHP CH3NH3PbBr3,which is as short as 0.21 ps.In comparison,the inorganic Cs-based LHP CsPbBr3 exhibited a longer cooling time of around 0.59 ps due to different phonon contributions.These results provide us new insights into the optimal design of hot-carrier solar cells and highlight the potential of LHP materials in advancing solar cell technology.

    Structural color of metallic glass through picosecond laser

    张月娥童星闫玉强曹硕...
    135-144页
    查看更多>>摘要：The alteration in surface color of metallic glasses(MGs)holds great significance in the context of microstructure design and commercial utility.It is essential to accurately describe the structures that are formed during the laser and color separation processes in order to develop practical laser coloring applications.Due to the high oxidation sensitivity of La-based metallic glass,it can broaden the color range but make it more complex.Structure coloring by laser processing on the surface of La-based metallic glass can be conducted after thermoplastic forming.It is particularly important to clarify the role of structure and composition in the surface coloring process.The aim is to study the relationship between amorphous surface structural color,surface geometry,and oxide formation by laser processing in metallic glasses.The findings revealed that the periodic structure primarily determines the surface color at laser energy densities below 1.0 J/mm2.In contrast,the surface color predominantly depends on the proportion of oxides that are formed when energy densities exceed 1.0 J/mm2.Consequently,this study provides a novel concept for the fundamental investigation of laser coloring and establishes a new avenue for practical application.

    On fractional discrete financial system:Bifurcation,chaos,and control

    Louiza DiabiAdel OuannasAmel HioualShaher Momani...
    145-157页
    查看更多>>摘要：The dynamic analysis of financial systems is a developing field that combines mathematics and economics to under-stand and explain fluctuations in financial markets.This paper introduces a new three-dimensional(3D)fractional financial map and we dissect its nonlinear dynamics system under commensurate and incommensurate orders.As such,we evaluate when the equilibrium points are stable or unstable at various fractional orders.We use many numerical methods,phase plots in 2D and 3D projections,bifurcation diagrams and the maximum Lyapunov exponent.These techniques reveal that financial maps exhibit chaotic attractor behavior.This study is grounded on the Caputo-like discrete operator,which is specifically influenced by the variance of the commensurate and incommensurate orders.Furthermore,we confirm the presence and measure the complexity of chaos in financial maps by the 0-1 test and the approximate entropy algorithm.Additionally,we offer nonlinear-type controllers to stabilize the fractional financial map.The numerical results of this study are obtained using MATLAB.

    Single pair of charge-2 Dirac and charge-2 Weyl phonons in GeO2

    何东昌刘嘉希刘培涛李江旭...
    158-163页
    查看更多>>摘要：The presence of a pair of Weyl and Dirac points(WP-DP)in topological semimetal states is intriguing and sought after due to the effects associated with chiral topological charges.However,identifying these states in real materials poses a significant challenge.In this study,by means of first-principles calculations we predict the coexistence of charge-2 Dirac and charge-2 Weyl phonons at high-symmetry points within a noncentrosymmetric P41212 space group.Furthermore,we propose GeO2 as an ideal candidate for realizing these states.Notably,we observe two distinct surface arcs that connect the Dirac and Weyl points across the entire Brillouin zone,which could facilitate their detection in future experimental investigations.This study not only presents a tangible material for experimentalists to explore the topological properties of WP-DP states but also opens up new avenues in the quest for ideal platforms to study chiral particles.

    164-172页
    查看更多>>摘要：The data post-processing scheme based on two-way classical communication(TWCC)can improve the tolerable bit error rate and extend the maximal transmission distance when used in a quantum key distribution(QKD)system.In this study,we apply the TWCC method to improve the performance of reference-frame-independent quantum key distribu-tion(RFI-QKD),and analyze the influence of the TWCC method on the performance of decoy-state RFI-QKD in both asymptotic and non-asymptotic cases.Our numerical simulation results show that the TWCC method is able to extend the maximal transmission distance from 175 km to 198 km and improve the tolerable bit error rate from 10.48％to 16.75％.At the same time,the performance of RFI-QKD in terms of the secret key rate and maximum transmission distance are still greatly improved when statistical fluctuations are considered.We conclude that RFI-QKD with the TWCC method is of practical interest.

    Interference-induced suppression of particle emission from a Bose-Einstein condensate in lattice with time-periodic modulations

    赖龙泉李照
    173-179页
    查看更多>>摘要：Emission of matter-wave jets from a parametrically driven condensate has attracted significant experimental and theoretical attention due to the appealing visual effects and potential metrological applications.In this work,we investigate the collective particle emission from a Bose-Einstein condensate confined in a one-dimensional lattice with periodically modulated interparticle interactions.We give the regimes for discrete modes,and find that the emission can be distinctly suppressed.The configuration induces a broad band,but few particles are ejected due to the interference of the matter waves.We further qualitatively model the emission process and demonstrate the short-time behaviors.This engineering provides a way to manipulate the propagation of particles and the corresponding dynamics of condensates in lattices,and may find application in the dynamical excitation control of other nonequilibrium problems with time-periodic driving.
