    Suppression of stimulated Brillouin and Raman scatterings using an alternating frequency laser and transverse magnetic fields

    查看更多>>摘要：A novel scheme to suppress both stimulated Brillouin scattering(SBS)and stimulated Raman scattering(SRS)by combining an alternating frequency(AF)laser and a transverse magnetic field is proposed.The AF laser allows the laser frequency to change discretely and alternately over time.The suppression of SBS is significant as long as the AF difference is greater than the linear growth rate of SBS or the alternating time of the laser frequency is shorter than the linear growth time of SBS.However,the AF laser proves ineffective in suppressing SRS,which usually has a much higher linear growth rate than SBS.To remedy that,a transverse magnetic field is included to suppress the SRS instability.The electrons trapped in the electron plasma waves(EPWs)of SRS can be accelerated by the surfatron mechanism in a transverse magnetic field and eventually detrapped.While continuously extracting energy from EPWs,the EPWs are dissipated and the kinetic inflation of SRS is suppressed.The one-dimensional particle-in-cell simulation results show that both SBS and SRS can be effectively suppressed by combining the AF laser with a transverse magnetic field with tens of Tesla.The total reflectivity can be dramatically reduced by more than one order of magnitude.These results provide a potential reference for controlling SBS and SRS under the related parameters of inertial confinement fusion.

    Sensitivity investigation of 100-MeV proton irradiation to SiGe HBT single event effect

    冯亚辉郭红霞刘益维欧阳晓平...
    612-621页
    查看更多>>摘要：The single event effect(SEE)sensitivity of silicon-germanium heterojunction bipolar transistor(SiGe HBT)irradiated by 100-MeV proton is investigated.The simulation results indicate that the most sensitive position of the SiGe HBT device is the emitter center,where the protons pass through the larger collector-substrate(CS)junction.Furthermore,in this work the experimental studies are also carried out by using 100-MeV proton.In order to consider the influence of temperature on SEE,both simulation and experiment are conducted at a temperature of 93 K.At a cryogenic temperature,the carrier mobility increases,which leads to higher transient current peaks,but the duration of the current decreases significantly.Notably,at the same proton flux,there is only one single event transient(SET)that occurs at 93 K.Thus,the radiation hard ability of the device increases at cryogenic temperatures.The simulation results are found to be qualitatively consistent with the experimental results of 100-MeV protons.To further evaluate the tolerance of the device,the influence of proton on SiGe HBT after gamma-ray(60Coy)irradiation is investigated.As a result,as the cumulative dose increases,the introduction of traps results in a significant reduction in both the peak value and duration of the transient currents.

    Effect of grain size on gas bubble evolution in nuclear fuel:Phase-field investigations

    孙丹杨青峰赵家珺高士鑫...
    622-632页
    查看更多>>摘要：Numerous irradiation-induced gas bubbles are created in the nuclear fuel during irradiation,leading to the change of microstructure and the degradation of mechanical and thermal properties.The grain size of fuel is one of the important factors affecting bubble evolution.In current study,we first predict the thermodynamic behaviors of point defects as well as the interplay between vacancy and gas atom in both UO2 and U3Si2 according to ab initio approach.Then,we establish the irradiation-induced bubble phase-field model to investigate the formation and evolution of intra-and inter-granular gas bubbles.The effects of fission rate and temperature on the evolutions of bubble morphologies in UO2 and U3Si2 have been revealed.Especially,a comparison of porosities under different grain sizes is examined and analyzed.To understand the thermal conductivity as functions of grain size and porosity,the heat transfer capability of U3Si2 is evaluated.

    Simulation of space heavy-ion induced primary knock-on atoms in bipolar devices

    633-641页
    查看更多>>摘要：Bipolar junction transistors(BJTs)are often used in spacecraft due to their excellent working characteristics.However,the complex space radiation environment induces primary knock-on atoms(PKAs)in BJTs through collisions,resulting in hard-to-recover displacement damage and affecting the performance of electronic components.In this paper,the properties of PKAs induced by typical space heavy ions(C,N,O,Fe)in BJTs are investigated using Monte Carlo simulations.The simulated results show that the energy spectrum of ion-induced PKAs is primarily concentrated in the low-energy range(17 eV-100 eV)and displays similar features across all tested ions.The PKAs induced by the collision of energetic ions have large forward scattering angles,mainly around 88°.Moreover,the distribution of PKAs within a transistor as a function of depth displays a peak characteristic,and the peak position is linearly proportional to the incident energy at a certain energy range.These simulation outcomes serve as crucial theoretical support for long-term semiconductor material defect evolution and ground testing of semiconductor devices.

    Linear magnetoresistance and structural distortion in layered SrCu4-xP2 single crystals

    聂勇陈正韦文森李慧杰...
    653-657页
    查看更多>>摘要：We report a systematic study on layered metal SrCu4-xP2 single crystals via transport,magnetization,thermodynamic measurements and structural characterization.We find that the crystals show large linear magnetoresistance without any sign of saturation with a magnetic field up to 30 T.We also observe a phase transition with significant anomalies in resistivity and heat capacity at Tp～140 K.Thermal expansion measurement reveals a subtle lattice parameter variation near Tp,i.e.,△Lc/Lc～0.062％.The structural characterization confines that there is no structure transition below and above Tp.All these results suggest that the nonmagnetic transition of SrCu4-xP2 could be associated with structural distortion.

    Geometries and electronic structures of ZrnCu(n=2-12)clusters:A joint machine-learning potential density functional theory investigation

    王一志崔秀花刘静井群...
    658-666页
    查看更多>>摘要：Zr-based amorphous alloys have attracted extensive attention because of their large glassy formation ability,wide supercooled liquid region,high elasticity,and unique mechanical strength induced by their icosahedral local structures.To determine the microstructures of Zr-Cu clusters,the stable and metastable geometry of ZrnCu(n=2-12)clusters are screened out via the CALYPSO method using machine-learning potentials,and then the electronic structures are in-vestigated using density functional theory.The results show that the ZrnCu(n ≥ 3)clusters possess three-dimensional geometries,ZrnCu(n ≥ 9)possess cage-like geometries,and the Zr12Cu cluster has icosahedral geometry.The binding energy per atom gradually gets enlarged with the increase in the size of the clusters,and ZrnCu(n=5,7,9,12)have relatively better stability than their neighbors.The magnetic moment of most ZrnCu clusters is just 1μB,and the main components of the highest occupied molecular orbitals(HOMOs)in the Zr12Cu cluster come from the Zr-d state.There are hardly any localized two-center bonds,and there are about 20 σ-type delocalized three-center bonds.

    Temperature effect on nanotwinned Ni under nanoindentation using molecular dynamic simulation

    667-677页
    查看更多>>摘要：Temperature effect on atomic deformation of nanotwinned Ni(nt-Ni)under localized nanoindentation is investigated in comparison with nanocrystalline Ni(nc-Ni)through molecular simulation.The nt-Ni exhibits enhanced critical load and hardness compared to nc-Ni,where perfect,stair-rod and Shockley dislocations are activated at(1(1)1),((1)11)and(11(1))slip planes in nt-Ni compared to only Shockley dislocation nucleation at(1(1)1)and((1)11)slip planes ofnc-Ni.The nt-Ni exhibits a less significant indentation size effect in comparison with nc-Ni due to the dislocation slips hindrance of the twin boundary.The atomic deformation associated with the indentation size effect is investigated during dislocation transmission.Different from the decreasing partial slips parallel to the indenter surface in nc-Ni with increasing temperature,the temperature-dependent atomic deformation of nt-Ni is closely related to the twin boundary:from the partial slips parallel to the twin boundary(～10 K),to increased confined layer slips and decreased twin migration(300 K-600 K),to decreased confined layer slips and increased dislocation interaction of dislocation pinning and dissociation(900 K-1200 K).Dislocation density and atomic structure types through quantitative analysis are implemented to further reveal the above-mentioned dislocation motion and atomic structure alteration.Our study is helpful for understanding the temperature-dependent plasticity of twin boundary in nanotwinned materials.

    Atomistic evaluation of tension-compression asymmetry in nanoscale body-centered-cubic AlCrFeCoNi high-entropy alloy

    邢润龙刘雪鹏
    678-688页
    查看更多>>摘要：The tension and compression of face-centered-cubic high-entropy alloy(HEA)nanowires are significantly asymmet-ric,but the tension-compression asymmetry in nanoscale body-centered-cubic(BCC)HEAs is still unclear.In this study,the tension-compression asymmetry of the BCC AlCrFeCoNi HEA nanowire is investigated using molecular dynamics simulations.The results show a significant asymmetry in both the yield and flow stresses,with BCC HEA nanowire stronger under compression than under tension.The strength asymmetry originates from the completely different defor-mation mechanisms in tension and compression.In compression,atomic amorphization dominates plastic deformation and contributes to the strengthening,while in tension,deformation twinning prevails and weakens the HEA nanowire.The tension-compression asymmetry exhibits a clear trend of increasing with the increasing nanowire cross-sectional edge length and decreasing temperature.In particular,the compressive strengths along the[001]and[111]crystallographic ori-entations are stronger than the tensile counterparts,while the[110]crystallographic orientation shows the exactly opposite trend.The dependences of tension-compression asymmetry on the cross-sectional edge length,crystallographic orientation,and temperature are explained in terms of the deformation behavior of HEA nanowire as well as its variations caused by the change in these influential factors.These findings may deepen our understanding of the tension-compression asymmetry of the BCC HEA nanowires.

    Determining Hubbard U of VO2 by the quasi-harmonic approximation

    孔龙娟陆雨航庄新莹周志勇...
    689-697页
    查看更多>>摘要：Vanadium dioxide VO2 is a strongly correlated material that undergoes a metal-to-insulator transition around 340 K.In order to describe the electron correlation effects in VO2,the DFT+U method is commonly employed in calculations.However,the choice of the Hubbard U parameter has been a subject of debate and its value has been reported over a wide range.In this paper,taking focus on the phase transition behavior of VO2,the Hubbard U parameter for vanadium oxide is determined by using the quasi-harmonic approximation(QHA).First-principles calculations demonstrate that the phase transition temperature can be modulated by varying the U values.The phase transition temperature can be well reproduced by the calculations using the Perdew-Burke-Ernzerhof functional combined with the U parameter of 1.5 eV.Additionally,the calculated band structure,insulating or metallic properties,and phonon dispersion with this U value are in line with experimental observations.By employing the QHA to determine the Hubbard U parameter,this study provides valuable insights into the phase transition behavior of VO2.The findings highlight the importance of electron correlation effects in accurately describing the properties of this material.The agreement between the calculated results and experimental observations further validates the chosen U value and supports the use of the DFT+U method in studying VO2.
