The piezoelectric photo-thermal (PPT) and the surface photo-voltage (SPV) spectra of GaAs/AlAs short …-period superlattices (SPS)-confined GaAs single-quantum well (SQW) were measured. The electron nonradiative transitions within GaAs-SQW and … from the exciton transition of e1-hh1 and e1-lh1 within GaAs-SQW were observed. These peak intensities showed the opposite …
