Abstract
We have calculated the tunneling of holes in single-barrier and double-barrier GaAs/AlGaAs diodes using a ten-band, empirical tight-binding model. Transfer matrices are used to model the wave-function on a layer-by-layer level allowing for a simple, transparent imposition of an electric field, and the mixing of heavy, light and splitoff valence band states. Transmission resonances have been found, and hole currents calculated at 77 degrees K. Mixing of different hole states has been examined as a function of aluminum fraction and thickness of the barriers and well.
