Modeling of intersubband transitions in ZnO/ZnMgO Coupled Quantum Wells
Апстракт
In recent years ZnO has become a popular semiconductor withmany potential applications in infra-red and THz optical devices owing to awide direct bandgap (3.4 eV) in combination with relatively high exciton binding energy (60 meV) [1]-[2]. In this work, we model the electronic structure of coupled oxide-semiconductor quantum wells by numerically solving the system of coupled Schrödinger-Poisson equations self-consistently (Fig. 1).We compare the obtained results with the recent experimental data[3] and analyze howthe variation of the layers’thicknesses affects the energy states. In addition, we examine the influence of doping to assess the differences between single well and two wells’cases, for the purpose ofdesigning more complex multi-well optical system in the future.
