Abstract
The Wannier exciton properties in a single quantum well (SQW) of Zn(S,Se)/ZnS strained materials are reproduced by an accurate variational envelope function. A systematic study of binding energy and oscillator strength is performed as a function of well thicknesses and strain parameter values. Optical response and second harmonic generation effects (SHG) in asymmetric single quantum wells (ASQWs) is computed and briefly discussed.
