Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

The elastic scattering angular distributions of ^(13)C at 340 MeV and ^(14)C at 294 MeV and 342 MeV on a ^(208)Pb target,which correspond to approximately five times the Coulomb barriers,were measured at the Radioactive Ion Beam Line in Lanzhou.The data were analyzed within the optical model and continuum-discretized coupled-channels(CDCC)framework,and the results of both calculations could effectively account for the experimental data.The differential cross sections of elastic scattering revealed no particular suppression at the Coulomb nuclear interference peak angles,suggesting that the breakup coupling effects on the elastic scattering angular distributions were negligibly small in this incident energy region.The contributions from the couplings with inelastic states to the elastic cross sections were of minor importance within the angular range covered by these experiments.

Brain-computer interfaces(BCIs),invasive or non-invasive,have projected unparalleled vision and promise for assisting patients in need to better their interaction with the surroundings.Inspired by the BCI-based rehabilitation technologies for nerve-system impairments and amputation,we propose an electromagnetic brain-computer-metasurface(EBCM)paradigm,regulated by human’s cognition by brain signals directly and non-invasively.We experimentally show that our EBCM platform can translate human’s mind from evoked potentials of P300-based electroencephalography to digital coding information in the electromagnetic domain non-invasively,which can be further processed and transported by an information metasurface in automated and wireless fashions.Directly wireless communications of the human minds are performed between two EBCM operators with accurate text transmissions.Moreover,several other proof-of-concept mind-control schemes are presented using the same EBCM platform,exhibiting flexibly-customized capabilities of information processing and synthesis like visual-beam scanning,wave modulations,and pattern encoding.

Metasurfaces are subwavelength structured thin films consisting of arrays of units that allow the control of polarization,phase,and amplitude of light over a subwavelength thickness.Recent developments in topological photonics have greatly broadened the horizon in designing metasurfaces for novel functional applications.In this review,we summarize recent progress in the research field of topological metasurfaces,first from the perspectives of passive and active in the classical regime,and then in the quantum regime.More specifically,we begin by examining the passive topological phenomena in two-dimensional photonic systems,including both time-reversal broken systems and time-reversal preserved systems.Subsequently,we discuss the cutting-edge studies of active topological metasurfaces,including nonlinear topological metasurfaces and reconfigurable topological metasurfaces.After overviewing topological metasurfaces in the classical regime,we show how they could provide a new platform for quantum information and quantum many-body physics.Finally,we conclude and describe some challenges and future directions of this fast-evolving field.

Structural, optical, and thermal properties of MAX-phase Cr2AlB2

引用

Frontiers of physics 2018年第2期13卷 93-101页

作者： xiao-Hong Li Hong-ling Cui Rui-Zhou Zhang College of Physics and engineering Henan University of Science and Technology Luoyang 471023 China department of Chemistry Nanjing University of Science and Technology Nanjing 210094 China Henan Key Laboratory of Photoelectric Energy Storage Materials and Applications Luoyang 471023 China

First-principles calculations of the structural, optical, and thermal properties of Cr2AlB2 are performed using the pseudopotential plane-wave method within the generalized gradient approximation （GGA）. Calculation of the elastic constant and phonon dispersion indicates that Cr2AlB2 is mechanically and thermodynamically stable. Analysis of the band structure and density of states indicates that Cr2AlB2 is metallic. The thermal properties under increasing temperature and pressure are investigated using the quasi-harmonic Debye model. The results show that anharmonic effects on Cr^AlB~ are important at low temperature and high pressure. The calculated equilibrium primitive cell volume is 95.91 ~3 at T = 300 K, P - 0 GPa. The ability of Cr2AlB2 to resist volume changes becomes weaker with increasing temperature and stronger with increasing pressure. Analysis of optical properties of Cr2AlB2 shows that the static dielectric function of Cr2AlB2 is 53.1, and the refractive index no is 7.3. If the incident light has a frequency exceeding 16.09 eV, which is the plasma frequency of Cr2AlB2, Cr2AlB2 changes from metallic to dielectric material.

Strong spin frustration and magnetism in kagoméantiferromagnets LnCu_(3)(OH)_(6)Br_(3)(Ln=Nd,Sm,and Eu)

作者：钟金群余振伟岳小宇王义炎梁慧孙燕吴丹丹丁宗玲孙进孙学峰李秋菊 School of Materials science and engineering Anhui UniversityHefei 230601China Institute of Physical science and Information technology Anhui UniversityHefei 230601China department of Physics and Key Laboratory of Strongly-Coupled Quantum Matter Physics(CAS)University of Science and Technology of ChinaHefei 230026China School of Physics and Optoelectronic engineering Anhui UniversityHefei 230601China School of optical and Electronic Information Suzhou City UniversitySuzhou 215104China

To study the effects of lanthanide ions on the geometrically frustrated antiferromagnets and their magnetic properties,we grew high-quality single crystals of LnCu_(3)(OH)_(6)Br_(3)(Ln=Nd,Sm,and Eu)by hydrothermal method and studied their crystal structures and magnetic properties.The refinements of the crystal structure referred to the powder x-ray diffraction data show that LnCu_(3)(OH)_(6)Br_(3)adopt a Kapellasite-type layer structure,which is isostructural to their chlorine analogue.Magnetic susceptibilities demonstrate that LnCu_(3)(OH)_(6)Br_(3)have strong antiferromagnetic coupling and a pronounced magnetic frustration effect.Magnetization measurements indicate canted antiferromagnetic ordering of Cu^(2+)ions around 16 K within the kagoméplane and weak ferromagnetic coupling.Moreover,shoulder-like anomalies in specific heat around 16 K could be a signature of emergent of magnetic ordering.The low-temperature negative magnetization and specific heat of LnCu_(3)(OH)_(6)Br_(3)(Ln=Nd,Sm,and Eu)indicate that Ln^(3+)ions induce more exotic magnetic ground state properties.
