Photoluminescence of extremely thin InGaAs/InP Single Quantum Wells grown by Organometallic Vapor Phase Epitaxy
Abstract
The optical properties of extremely thin In0.53Ga0.47As/InP single quantum wells (SQWs) grown by Organometallic Vapor Phase Epitaxy (OMVPE) were extensively investigated by photoluminescence spectroscopy (PL). The PL spectra of 3 samples with different well widths of 2 monolayers (ML), 3 ML, and 4ML were carried out. The spectra exhibit a single luminescence peak, corresponding to the recombination between the first electron subband and the first heavy-hole subband (e1-hh1).
