Abstract
The calculation of multiband tunneling in semiconductor multilayer structures, including resonant tunneling structures, has been hampered by computational problems such as limitations of numerical precision or excessive requirements of computer time. Recently, a few techniques have appeared which help eliminate these limitations. Here we present a related method and its derivation that solves the tight-binding equations for tunneling problems.Keywords
