Abstract
As a classic model, the multiple potential barrier structure has been widely studied in the last decades. In this work, we investigate the transmission coefficient of electron tunneling through multiple quantum walls based on ZnSe/BeTe heterojunction. At first, based on the one-dimensional stationary Schrödinger equation and its boundary condition, the equation set is set up. Then, by using the matrix method, the transmission coefficient can be solved by Matlab. The relationship of the transmission coefficient to the energy of the electron, the width of the well, the width of the barrier, the number of barriers, and the potential barrier are simulated. According to the analysis, some phenomena like gap region and miniband can be observed. The number of resonance states in minibands increases when the number of barriers increases while the zones of minibands approximately remain unchanged. This work can be the guide to designing multiple potential barrier nanostructures.
