Abstract

Using the transfer matrix method and the Ben Daniel-Duke equation for variable mass electrons propagation, we calculate the transmittance for a finite superlattice where the potential barriers height follows a linear dependence like that of an inverted “V” letter. The energy dependence of the transmittance presents intervals of stopbands and nearly flat passbands. We calculate these properties for several numbers of barriers as well as for different barrier and wells widths and compare those with a regular superlattice.
