Non-Superconducting Non-Abelian Statistics in One-Dimensional Topological Insulators
Zhigang Song
Topological materials are of great interest for applications in quantum computing, providing intrinsic robustness against environmental noises. A popular direction is to look for M…
Conetronics in 2D Metal-Organic Frameworks: Double Dirac Cones, Magnetic Half Dirac Cones and Quantum Anomalous Hall Effect
Menghao Wu, Zhijun Wang, Junwei Liu +8
Based on recently synthesized Ni3C12S12 class 2D metal-organic frameworks, we predict electronic properties of M3C12S12 and M3C12O12, where M is Zn, Cd, Hg, Be, or Mg with no M orb…
Giant Piezoelectricity in Monolayer Group IV Monochalcogenides: SnSe, SnS, GeSe and GeS
Ruixiang Fei, Wenbin Li, Ju Li +1
We predict enormous piezoelectric effects in intrinsic monolayer group IV monochalcogenides (MX, M=Sn or Ge, X=Se or S), including SnSe, SnS, GeSe and GeS. Using first-principle si…
Does P-type Ohmic Contact Exist in WSe2-metal Interfaces?
Yangyang Wang, Ruoxi Yang, Ruge Quhe +9
Formation of low-resistance metal contacts is the biggest challenge that masks the intrinsic exceptional electronic properties of 2D WSe2 devices. We present the first comparative…
Monolayer Phosphorene-Metal Interfaces
Yuanyuan Pan, Yangyang Wang, Meng Ye +9
Recently, phosphorene electronic and optoelectronic prototype devices have been fabricated with various metal electrodes. We systematically explore for the first time the contact p…
Silicene Spintronics
Yangyang Wang, Ruge Quhe, Dapeng Yu +2
Spintronics involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. The fascinating spin-resolved properties of graphene motivate n…
Piezoelectricity in Two-Dimensional Group III Monochalcogenides
Wenbin Li, Ju Li
We find that several layer-phase group-III monochalcogenides, including GaS, GaSe and InSe, are piezoelectric in the monolayer form. First-principles calculations reveal that the p…
Deformation-Driven Diffusion and Plastic Flow in Two-Dimensional Amorphous Granular Pillars
Wenbin Li, Jennifer M. Rieser, Andrea J. Liu +2
We report a combined experimental and simulation study of deformation-induced diffusion in compacted two-dimensional amorphous granular pillars, in which thermal fluctuations play…
Envelope function method for electrons in slowly-varying inhomogeneously deformed crystals
Wenbin Li, Xiaofeng Qian, Ju Li
We develop a new envelope-function formalism to describe electrons in slowly-varying inhomogeneously strained semiconductor crystals. A coordinate transformation is used to map a d…
Quantum Spin Hall Effect and Topological Field Effect Transistor in Two-Dimensional Transition Metal Dichalcogenides
Xiaofeng Qian, Junwei Liu, Liang Fu +1
We report a new class of large-gap quantum spin Hall insulators in two-dimensional transition metal dichalcogenides, namely, MX with M=(Mo, W) and X=(S, Se, and Te), whose topo…
Topological Crystalline Insulator Nanomembrane with Strain-Tunable Band Gap
Xiaofeng Qian, Liang Fu, Ju Li
The ability to fine-tune band gap and band inversion in topological materials is highly desirable for the development of novel functional devices. Here we propose that the electron…
