GOLD-GERMANIUM CONTACTS ON GALLIUM ARSENIDE

Abstract
The gold-germanium/gallium arsenide interface was investigated using atom-probe analysis and transmission electron microscopy. When thin films were deposited on an oxidized surface small islands formed. No gold or germanium was detected between islands. One island was analysed and it contained germanium, gold and a substantial amount of oxygen. No outdiffusion of gallium or arsenic to the island was observed.
