Popis:	The optical properties of ZnOS/ZnO quantum-well (QW) structures, considering piezoelectric and spontaneous polarizations, are investigated by using many-body effects. The ZnOS/ZnO QW structure is found to have small optical gain because SP polarizations have a negative sign in the well and increase with the inclusion of S. These results demonstrate that ZnOS/ZnO QW structure have a strong internal field. This structure offers further flexibility for band-gap engineering and potentially facilitates p-type doping of ZnO-based light-emitting diodes.
