摘要：
In this paper, by using the envelope function method (EFM) coupled to the transfer matrix technique, we report the calculations of both the conduction and the valence subbands of parabolic quantum wells (PQW) of AlGaAs. We note that the conduction subbands are equidistant for all the values of k. We also observe that the valence subbands for PQW show a lower mixing compared to the square quantum wells (SQW) and are less influenced by a longitudinal electric field.
