摘要：
The subband energy of an Inverted core shell structure is computed for a GaAs/AlxGa1-xAs Quantum dot in the effective mass approximation. The effect of shell thickness and size of the dot on the subband energy is studied. It is seen that the subband energy is affected by core as well as shell size. These studies aid in the construction of electronic levels of the system and hence can act as a probe to study the fine structure splitting of excitonic levels. The change in subband energy is larger for change in shell thickness value than for core radius. Subband energy decreases as aluminum concentration decreases. For lower shell thickness there is substantial change in the subband energy between aluminum concentration of 0.4 and 0.1. (C) 2019 Elsevier Ltd. All rights reserved.
