Modeling of the Optical Properties of a Barrier, Reservoir, and Quantum-Well Electron Transfer Structure

Research output: Contribution to journalArticle

Abstract

We present a novel numerical simulator, OPCONS, for the analysis of the optical properties of InxGa1-xAs/In1-yAlyAs multiple-quantum-well heterostructures with tunable charge density. The influence of carriers and dopant ion charges on the electronic properties are simulated with a self-consistent Poisson-Schrodinger solver. The calculated optical constants of the quantum well reproduce well the experimental electrooptic characteristics. The code implements the drift-diffusion and thermionic emission currents to calculate the I-V characteristics and shows a good agreement with the experimental data.
