Abstract
The nondestructive photoluminescence technology has been introduced to test and evaluate the growth of InGaAs/GaAs Single-Quantum Well (SQW) by using Molecular Beam Epitaxy (MBE) technology. The experiments are carried out at different temperature in order to test the effect of variation of gap energy. When temperature varied, the lineshape of spectra changed, particular in the short wavelength part. The wavelength of emit light peak blue shift as well. We indicate that the main mechanism of the radiative recombination at high temperature is of band-to-band origin. However, at low temperature, exciton recombination is prevailing.
