Mermin-Wagner Theorem, Flexural Modes, and Degraded Carrier Mobility in Two-Dimensional Crystals with Broken Horizontal Mirror Symmetry
(Amer Physical Soc, 2016-04-11)
We show that the electron mobility in ideal, free-standing two-dimensional "buckled" crystals with broken horizontal mirror (σ_h) symmetry and Dirac-like dispersion (such as silicene and germanene) is dramatically affected ...
Theoretical Simulation of Negative Differential Transconductance in Lateral Quantum Well nMOS Devices
(American Institute of Physics Inc, 2017-01-23)
We present a theoretical study of the negative differential transconductance (NDT) recently observed in the lateral-quantum-well Si n-channel field-effect transistors J. Appl. Phys. 118, 124505 (2015)]. In these devices, ...
Carrier Transport in Two-Dimensional Topological Insulator Nanoribbons in the Presence of Vacancy Defects
(IOP Publishing Ltd, 2019-02-05)
Using the non-equilibrium Green's function formalism, we study carrier transport through imperfect two-dimensional (2D) topological insulator (TI) ribbons. In particular, we investigate the effect of vacancy defects on the ...
