Some III-V digital alloy avalanche photodiodes exhibit low excess noise.These alloys have low hole ionization coefficients due to presence of small'minigaps', enhanced effective mass and large separation between light-hole andsplit-off bands in the valence band. In this letter, an explanation for theformation of the minigaps using a tight binding picture is provided.Furthermore, we demonstrate that decreasing substrate lattice constant canincrease the minigap size and mass in the transport direction. This leads toreduced quantum tunneling and phonon scattering of the holes. Finally, weillustrate the band structure modification with substrate lattice constant forother III-V digital alloys.
