Query: An Extended H\"uckel Study of the Electronic Properties of III-V
  Compounds and Their Alloys   In this work, we performed tight binding calculations of the electronic
structure of III-V semiconductors compounds and their alloys based on the
Extended H\"uckel Theory (EHT), where the H\"uckel parameters for the binary
compounds were generated following a simulated annealing procedure. In
particular, this article is focused on the dependency between band gap and the
applied pressure and also the alloy composition.
