Paper Abstract

An Attempt is made to study the photo-emission from bulk specimen, inversion layer, quantum wells, quantum wires (QWs) and quantum dots (QDs) of non-linear optical materials by using the generalized electron energy spectrum and taking n-CdGeAs2 as an example. We have also studied these same dependences in II2 - VI (CdS/CdTe) and HgTe/CdTe superlattices (SLs) under magnetic quantization. It is found that in all the cases the photo-emission exhibits ladder-like dependences with increasing photon energy. The photo-emission is greatest for HgTe/CdTe SL and laest for bulk n-CdGeAs2
