Paper Abstract

The photoreflectance has been measured on InGaAs/GaAs multiple strained quantum wells structures at room temperature. The Franz-Keldysh Oscillation (FKOs) features are clearly observed on photoreflectance spectra. Based on FKOs features above the energy band gap, the built-in electric field was studied by conventional FKOs calculation and the Fast Fourier Transform, and Airy function fit techniques. The built-in electric fields were evaluated and discussed. The results show that Fast Fourier Transform could provide an accurate and fast method to calculate the built-in electric field.
