Abstract:   (998 Views)

In the present work we have studied optical properties of quantum ring based on MQW using tight-binding method considering the effects of well number and confinement potential. For two rings with same circumstance of 60 nm and different number of wells, 2 and 4,   wave functions and energy eigenvalues have been calculated.  The results shows with increasing well numbers the energy eigenvalues increases and the wave function confined in the well centers. Also with increasing well numbers from two to four wells, the absorption coefficient of structure decrease %13 and the peak of absorption has 15meV blue shift

Keywords: Tight Binding Method, Quantum Ring, Multiple Quantum Well, Absorption.
