Figure 1From: Study of the vertical transport in p-doped superlattices based on group III-V semiconductors Schematic representation of a SL band structure used in this study. Minibands for heavy hole levels, ε hh,1 , minigaps, subbands, and Fermi level, E F, are shown. The zero of energy was considered at the top of the Coulomb potential at the barrier. Horizontal dashed lines indicate the bottom of the first miniband and the top of the second miniband, respectively.Back to article page
