Ultrathin epitaxial film of AIAs deposited on GaAs substrate to serve as Schottky barrier and/or as barrier to diffusion. Deposited without interrupting processing vacuum in which substrate deposited and in which any subsequent layers deposited. In new technique, epitaxial film of AIAs deposited directly on GaAs substrate to depth of only two atomic layers - less than 1 nanometer thick. Film thin enough so it does not constitute electronic barrier, but thick enough to act as barrier to interdiffusion of gold and GaAs. Film also used as barrier to interdiffusion of dopants at heterojunctions.
