Abstract

In this work we have investigated the variational parameters of a trial wave function which usually apply for investigation of excition properties in GaAs/AlGaAs quantum well structure. The interval of variation and physical meaning of these free parameters have been discussed. The tunneling behavior of an electron and hole and some other their physical properties have investigated..

Keywords
