    Combining electron microscopy with atomic-scale calculations—A personal perspective

    Sokrates T.Pantelides
    3-13页
    查看更多>>摘要：I had the privilege and the pleasure to work closely with Stephen J.Pennycook for about twenty years,having a group of post-docs and Vanderbilt-University graduate students embedded in his electron microscopy group at Oak Ridge National Laboratory,spending on average a day per week there.We combined atomic-resolution imaging of materials,electron-energy-loss spectroscopy,and density-functional-theory calculations to explore and elucidate diverse materials phenomena,often resolving long-standing issues.This paper is a personal perspective of that journey,highlighting a few examples to illustrate the power of combining theory and microscopy and closing with an assessment of future prospects.

    A universal resist-assisted metal transfer method for 2D semiconductor contacts

    刘轩冶李林璇尉驰俊宋鹏...
    14-22页
    查看更多>>摘要：With the explosive exploration of two-dimensional(2D)semiconductors for device applications,ensuring effective electrical contacts has become critical for optimizing device performance.Here,we demonstrate a universal resist-assisted metal transfer method for creating nearly free-standing metal electrodes on the SiO2/Si substrate,which can be easily transferred onto 2D semiconductors to form van der Waals(vdW)contacts.In this method,polymethyl methacrylate(PMMA)serves both as an electron resist for electrode patterning and as a sacrificial layer.Contacted with our transferred electrodes,MoS2 exhibits tunable Schottky barrier heights and a transition from n-type dominated to ambipolar conduction with increasing metal work functions,while InSe shows pronounced ambipolarity.Additionally,using a-In2Se3 as an example,we demonstrate that our transferred electrodes enhance resistance switching in ferroelectric memristors.Finally,the universality of our method is evidenced by the successful transfer of various metals with different adhesion forces and complex patterns.

    Pressure-induced structural transitions and metallization in ZrSe2

    23-28页
    查看更多>>摘要：High-pressure studies of two-dimensional materials have revealed numerous novel properties and physical mecha-nisms behind them.As a typical material of transition metal dichalcogenides(TMDs),ZrSe2 exhibits high carrier mobility,rich electronic states regulated by doping,and high potential in applications at ambient pressure.However,the properties of ZrSe2 under pressure are still not clear,especially for the structural and electrical properties.Here,we report the investi-gation of ZrSe2 under pressure up to 66.5 GPa by in-situ x-ray diffraction,Raman,electrical transport measurements,and first-principles calculations.Two structural phase transitions occur in ZrSe2 at 8.3 GPa and 31.5 GPa,from P-3m1 symme-try to P21/m symmetry,and finally transformed into a non-layer I4/mmm symmetry structure.Pressure-induced metallic transition is observed at around 19.4 GPa in phase Ⅱ which aligns well with the results of the calculation.Our work will help to improve the understanding of the evolution of the structure and electrical transport properties of two-dimensional materials.

    Pressure-induced superconductivity and phase transition in PbSe and PbTe

    29-37页
    查看更多>>摘要：The Ⅳ-Ⅵ semiconducting chalcogenides are a large material family with distinct physical behavior.Here,we sys-tematically investigate the effect of pressure on the electronic and crystal structures of PbSe and PbTe by combining high-pressure electrical transport and synchrotron x-ray diffraction(XRD)measurements.The resistivity of PbSe and PbTe changes dramatically under high pressure and a non-monotonic evolution of p(T)is observed.Both PbSe and PbTe are found to undergo semiconductor-metal transition upon compression and show superconductivity under higher pressure.The structural evolutions from the Fm3m to Pnma phase and then to the Pm3m phase in PbSe are verified by the x-ray diffraction.The present findings reveal the internal correlation between the structural evolution and the physical properties in lead chalcogenides.

    Design of superconducting compounds at lower pressure via intercalating XH4 molecules(X=B,C,and N)into fcc lattices

    查看更多>>摘要：Recently,many encouraging experimental advances have been achieved in ternary hydrides superconductors under high pressure.However,the extreme pressure required is indeed a challenge for practical application,which promotes a further exploration for high temperature(Tc)superconductors at relatively low pressure.Herein,we performed a systematic theoretical investigation on a series of ternary hydrides with stoichiometry AX2H8,which is constructed by interacting molecular XH4(X=B,C,and N)into the fcc metal A lattice under low pressure of 0-150 GPa.We uncovered five compounds which are dynamically stable below 100 GPa,e.g.,AcB2H8(25 GPa),LaB2H8(40 GPa),RbC2H8(40 GPa),CsC2H8(60 GPa),and SrC2H8(65 GPa).Among them,AcB2H8,which is energetically stable above 2.5 GPa,exhibits the highest Tc of 32 K at 25 GPa.The superconductivity originates mainly from the coupling between the electron of Ac atoms and the associated low-frequency phonons,distinct from the previous typical hydrides with H-derived superconductivity.Our results shed light on the future exploration of superconductivity among ternary compounds at low pressure.

    查看更多>>摘要：This work demonstrates a micron-sized nanosecond current pulse probe using a quantum diamond magnetometer.A micron-sized diamond crystal affixed to a fiber tip is integrated on the end of a conical waveguide.We demonstrate real-time visualization of a single 100 nanosecond pulse and discrimination of two pulse trains of different frequencies with a coplanar waveguide and a home-made PCB circuit.This technique finds promising applications in the display of electronic stream and can be used as a pulse discriminator to simultaneously receive and demodulate multiple pulse frequencies.This method of detecting pulse current is expected to provide further detailed analysis of the internal working state of the chip.

    51-66页
    查看更多>>摘要：In distributed quantum computing(DQC),quantum hardware design mainly focuses on providing as many as possible high-quality inter-chip connections.Meanwhile,quantum software tries its best to reduce the required number of remote quantum gates between chips.However,this"hardware first,software follows"methodology may not fully exploit the potential of DQC.Inspired by classical software-hardware co-design,this paper explores the design space of application-specific DQC architectures.More specifically,we propose AutoArch,an automated quantum chip network(QCN)structure design tool.With qubits grouping followed by a customized QCN design,AutoArch can generate a near-optimal DQC architecture suitable for target quantum algorithms.Experimental results show that the DQC architecture generated by AutoArch can outperform other general QCN architectures when executing target quantum algorithms.

    Nonlinear enhanced mass sensor based on optomechanical system

    满鑫鑫孙静张闻钊罗丽娟...
    67-74页
    查看更多>>摘要：A high-precision and tunable mass detection scheme based on a double-oscillator optomechanical system is proposed.By designating one of the oscillators as the detection port,tiny mass signals can be probed through the frequency shift of the output spectrum,utilizing the system's optomechanically induced transparency(OMIT)effect.By solving the output of the optical mode,we demonstrate that the system exhibits two OMIT windows due to the double-oscillator coupling,with one window being strongly dependent on the mass to be detected.Characterizing the spectrum around this window enables high magnification and precise detection of the input signal under nonlinear parameter conditions.Additionally,our scheme shows resilience to environmental temperature variations and drive strength perturbations.

    M2CS:A micro wave measurement and control system for large-scale superconducting quantum processors

    张家蔚孙炫东郭泽臣袁跃峰...
    75-87页
    查看更多>>摘要：As superconducting quantum computing continues to advance at an unprecedented pace,there is a compelling de-mand for the innovation of specialized electronic instruments that act as crucial conduits between quantum processors and host computers.Here,we introduce a microwave measurement and control system(M2CS)dedicated to large-scale super-conducting quantum processors.M2CS features a compact modular design that balances overall performance,scalability and flexibility.Electronic tests of M2CS show key metrics comparable to commercial instruments.Benchmark tests on transmon superconducting qubits further show qubit coherence and gate fidelities comparable to state-of-the-art results,confirming M2CS's capability to meet the stringent requirements of quantum experiments running on intermediate-scale quantum processors.The compact and scalable nature of our design holds the potential to support over 1000 qubits after upgrade in stability and integration.The M2CS architecture may also be adopted to a wider range of scenarios,including other quantum computing platforms such as trapped ions and silicon quantum dots,as well as more traditional applications like microwave kinetic inductance detectors and phased array radar systems.
