Role of Strain on Electronic and Mechanical Response of Semiconducting Transition-Metal Dichalcogenide Monolayers: an ab-initio study
David M. Guzman, Alejandro Strachan
We characterize the electronic structure and elasticity of monolayer transition-metal dichalcogenides MX2 (M=Mo, W, Sn, Hf and X=S, Se, Te) with 2H and 1T structures using fully re…
Tuning a Schottky barrier in a photoexcited topological insulator with transient Dirac cone electron-hole asymmetry
M. Hajlaoui, E. Papalazarou, J. Mauchain +19
The advent of Dirac materials has made it possible to realize two dimensional gases of relativistic fermions with unprecedented transport properties in condensed matter. Their phot…
An Environment-dependent Semi-Empirical Tight Binding Model Suitable for Electron Transport in Bulk Metals, Metal Alloys, Metallic Interfaces and Metallic Nanostructures II - Effect of Confinement and Homogeneous Strain on Cu Conductance
Ganesh Hegde, Michael Povolotskyi, Tillmann Kubis +2
The Semi-Empirical TB model developed in part I is applied to metal transport problems of current relevance in part II. A systematic study of the effect of quantum confinement, tra…
An Environment-dependent Semi-Empirical Tight Binding Model Suitable for Electron Transport in Bulk Metals, Metal Alloys, Metallic Interfaces and Metallic Nanostructures I - Model and Validation
Ganesh Hegde, Michael Povolotskyi, Tillmann Kubis +2
Semi-Empirical Tight Binding (TB) is known to be a scalable and accurate atomistic representation for electron transport for realistically extended nano-scaled semiconductor device…
Giant Quasiparticle Bandgap Modulation in Graphene Nanoribbons Supported on Weakly Interacting Surfaces
Xueping Jiang, Neerav Kharche, Paul Kohl +5
In general, there are two major factors affecting bandgaps in nanostructures: (i) the enhanced electron-electron interactions due to confinement and (ii) the modified self-energy o…
Stark Ionization of Atoms and Molecules within Density Functional Resonance Theory
Ask Hjorth Larsen, Umberto De Giovannini, Daniel Lee Whitenack +2
We show that the energetics and lifetimes of resonances of finite systems under an external electric field can be captured by Kohn--Sham density functional theory (DFT) within the…
Synthetic Graphene Grown by Chemical Vapor Deposition on Copper Foils
Ting Fung Chung, Tian Shen, Helin Cao +5
The discovery of graphene, a single layer of covalently bonded carbon atoms, has attracted intense interests. Initial studies using mechanically exfoliated graphene unveiled its re…
Molecular Doping of Multilayer MoS2 Field-effect Transistors: Reduction in Sheet and Contact Resistances
Yuchen Du, Han Liu, Adam T. Neal +2
For the first time, polyethyleneimine (PEI) doping on multilayer MoS2 field-effect transistors are investigated. A 2.6 times reduction in sheet resistance, and 1.2 times reduction…
Strain enhancement of high-k dielectric response in (La/Sc)2 O3 and LaScO3 : an ab-initio study
Stas M. Avdoshenko, Alejandro Strachan
We use density functional theory within the generalized gradient approximation to characterize the dielectric response of rare earth oxides: (La,Sc)2 O3 bixbyite, and LaScO3 perovs…
Geometric treatment of conduction electron scattering by crystal lattice strains and dislocations
Koushik Viswanathan, Srinivasan Chandrasekar
A theory for conduction electron scattering by inhomogeneous crystal lattice strains is developed, based on the differential geometric treatment of deformations in solids. The resu…
Spintronic Switches for Ultra Low Energy On-Chip and Inter-Chip Current-Mode Interconnects
Mrigank Sharad, Kaushik Roy
Energy-efficiency and design-complexity of high-speed on-chip and inter-chip data-interconnects has emerged as the major bottleneck for high-performance computing-systems. As a sol…
Ultra Low Power Associative Computing with Spin Neurons and Resistive Crossbar Memory
Mrigank Sharad, Deliang Fan, Kaushik Roy
Emerging resistive-crossbar memory (RCM) technology can be promising for computationally-expensive analog pattern-matching tasks. However, the use of CMOS analog-circuits with RCM…
Strain-induced topological insulator phase transition in HgSe
Lars Winterfeld, Luis A. Agapito, Jin Li +3
Using ab initio electronic structure calculations we investigate the change of the band structure and the nu_0 topological invariant in HgSe (non-centrosymmetric system) under two…
Metrics for measuring distances in configuration spaces
Ali Sadeghi, S. Alireza Ghasemi, Bastian Schaefer +3
In order to characterize molecular structures we introduce configurational fingerprint vectors which are counterparts of quantities used experimentally to identify structures. The…
