Abstract
We have performed first-principles local density calculations of sever al interfaces between GaN and AlN and studied their formation enthalpy and band offsets and the charge pileup at polar interfaces. Monte Car lo studies of the electrical characteristics of submicron HFET structu res reveal that the pyro- and piezoelectric moments of the nitrides ar e a key property for designing and optimizing future devices.
