It is difficult to apply the classical Poisson and drift\u2013diffusion (DD) model to direct modeling of carrier transport in superlattice<br>\n systems because quantum effects need to be considered. With the LL theory, it is possible to obtain the effective quantum potential seen<br>\n by carriers. By coupling the LL theory with the Poisson\u2013DD model and replacing the traditional conduction and valence potentials with<br>\n effective quantum potentials, it is possible to directly model carrier transport in a T2SL system. We compare the results of this approach<br>\n with experimental results and find very good agreement, which indicates that this method will provide an efficient tool for the T2SL design.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img fetchpriority=\"high\" decoding=\"async\" width=\"594\" height=\"570\" src=\"http:\/\/yrwu-wk.ee.ntu.edu.tw\/wp-content\/uploads\/2020\/01\/typeII-SL.gif\" alt=\"\" class=\"wp-image-912\"\/><\/figure>\n\n\n\n<p> Comparison of the LL \u00fe Poisson\u2013DD solver and the Poisson\u2013DD solver with a  bias of 0.5 V.
