Abstract

In this work, oscillator strength and QUANTUM EFFICIENCY of new spherical GaN/AlGaN quantum dot was investigated. In order to obtain these parameters, at first, Schrödinger equation is solved in GaN/AlGaN spherical coordinate system in effective mass approximation, and energy level, wave function and transition matrix element of the parameter are obtained. The results show that oscillator strength decreases with increase of mol fraction and dot size. This effect is more obvious for high mol fractions. With increasing mol fraction of defect, the peak of QUANTUM EFFICIENCY shows blue shift. Increasing the radius of core and shell causes the red shift of QUANTUM EFFICIENCY peak. The red and blue shifts can be very useful in tunning and controling the detector wavelenght range.
