Energy eigenvalue and tunneling effect of rectangular double quantum well

Abstract

In this research paper ,we study the energy eigenvalue and tunneling effect of rectangular double quantum well (RDQW) heterostructures composed of two different semiconductors. The heterostructure is denoted as B/W/B/W/B, where the heterostructure W and B acts as crystal wells and barriers, respectively. This confined heterostructure wells have quantized states. For this research we used analytical method and determined two transdental equations, and numerically we determined the energy eigenvalues of RDQW. We obtained wave states and energy eigenvalues with their transmission and reflection coefficients in the RDQW hetrostructure. However, we have also observed how the width of the wells can affect the transmission by increasing the thickness of the barriers. This study is important in developing photocells, photoswitching devices, optical filters, and other optoelectronic devices.
