Electrical control of inter-layer excitons in van der Waals heterostructures
A. Chaves, J. G. Azadani, V. Ongun Özçelik +2
We investigate excitons in stacked transition metal dichalcogenide (TMDC) layers under perpendicularly applied electric field, herein MoSe/WSe van der Waals heterostructure…
Enhanced interlayer neutral excitons and trions in trilayer van der Waals heterostructures
Chanyeol Choi, Jiahui Huang, Hung-Chieh Cheng +11
Vertically stacked van der Waals heterostructures constitute a promising platform for providing tailored band alignment with enhanced excitonic systems. Here we report observations…
Room-temperature perpendicular magnetization switching through giant spin-orbit torque from sputtered BixSe(1-x) topological insulator material
Mahendra DC, Mahdi Jamali, Jun-Yang Chen +9
The spin-orbit torque (SOT) arising from materials with large spin-orbit coupling promises a path for ultra-low power and fast magnetic-based storage and computational devices. We…
Semi-analytical model of the contact resistance in two-dimensional semiconductors
Roberto Grassi, Yanqing Wu, Steven J. Koester +1
Contact resistance is a severe performance bottleneck for electronic devices based on two-dimensional layered (2D) semiconductors, whose contacts are Schottky rather than Ohmic. Al…
Mode space approach for tight-binding transport simulations in graphene nanoribbon field-effect transistors including phonon scattering
Roberto Grassi, Antonio Gnudi, Ilaria Imperiale +3
In this paper, we present a mode space method for atomistic non-equilibrium Green's function simulations of armchair graphene nanoribbon FETs that includes electron-phonon scatteri…
Contact-induced negative differential resistance in short-channel graphene FETs
Roberto Grassi, Tony Low, Antonio Gnudi +1
In this work, we clarify the physical mechanism for the phenomenon of negative output differential resistance (NDR) in short-channel graphene FETs (GFETs) through non-equilibrium G…
