Theoretical Simulation of Negative Differential Transconductance in Lateral Quantum Well nMOS Devices

Vyas, P. B.; Naquin, C.; Edwards, H.; Lee, Mark; Vandenberghe, W. G.; Fischetti, Massimo V. (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, ...

Mermin-Wagner Theorem, Flexural Modes, and Degraded Carrier Mobility in Two-Dimensional Crystals with Broken Horizontal Mirror Symmetry

Fischetti, Massimo V.; Vandenberghe, William G. (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 ...
