摘要：
The traveling wave potential wells that are generated from a surface acoustic wave in the piezoelectric materials of semiconductor efficiently trap the created electron hole pairs, which is a potential method of the single-photon detectors. In this study, we report on a model that is used to study the correlation between radiative lifetime and periodical potential wells. We devised a Python program to numerically find the eigenstates in 1D periodical potential well system. The Schrodinger equation is solved to obtain electron and hole wave functions that are related to charge distribution. Then, we analyzed the impact of the potential well on the corresponding radiative lifetime of the system.
