The Layered Semiconductor Cu(Sb2S3)[AlCl4]

The Schrödinger-Poisson Selfconsistency in Layered Quantum Semiconductor Structures

We develop a selfconsistent solution of the Schrödinger and Poisson equations in semiconductor heterostructures with arbitrary doping profiles and layer geometries. An algorithm for this nonlinear problem is presented in a multiband k ·P framework for the electronic band structure using the finite element method. The discretized functional integrals associated with the Schrödinger and Poisson e...

Two-dimensional layered semiconductor/graphene heterostructures for solar photovoltaic applications.

Schottky barriers formed by graphene (monolayer, bilayer, and multilayer) on 2D layered semiconductor tungsten disulfide (WS2) nanosheets are explored for solar energy harvesting. The characteristics of the graphene-WS2 Schottky junction vary significantly with the number of graphene layers on WS2, resulting in differences in solar cell performance. Compared with monolayer or stacked bilayer gr...

Ab initio calculations and ellipsometry measurements of the optical properties of the layered semiconductor In4Se3

Simulation of ionic current through the nanopore in a double-layered semiconductor membrane.

We study the effects of different nanopore geometries (double-conical, single-conical, cylindrical) on the electrostatic potential distribution and ionic conductivity in a double-layered semiconductor nanopore device as functions of the applied membrane bias. Ionic current-voltage characteristics as well as their rectification ratios are calculated using a simple ion transport model. Based on o...
