Numerical Analysis of Surface Acoustic Wave Driven Carriers Transport in GaAs/AlGaAs Quantum Well

EasyChair Preprint 10043

Abstract

The surface acoustic waves (SAWS) with a strong enough piezoelectric fifield can capture and transport

electrons and holes. The presence of the surface acoustic waves and their photo-generated carriers transport properties

in the GaAs/AlGaAs quantum well (QW) is a potential scheme to achieve single photon sources and single photon

detectors. A fifinite difference method was developed as a conventional approach to the theoretical understandings of

the presence in the QW. The code was programmed in Python to stimulate the system. Conditions of different SAW

wavelengths and SAW intensities were investigated. The spatical separation and recombination time of the electrons

and holes could be obtained by the potential in the QW.

Keyphrases: Python, Single-photon devices, Surface acoustic waves, quantum well
