Optical properties of ZnO/(Zn, Mg)O quantum wells
... For type I QWs, where both electron and hole are confined in the same layer, the quantum-confined Stark effect (QCSE) red-shifts the fundamental optical transition. The internal electric field induces spatial separation of carriers having different charges. As a consequence, there is a decrease of t ...
