ABSTRACT
The Fe acceptor level in In1-xGaxAsyP1-y lattice matched to InP (x=0.47y) is investigated employing current-voltage characteristics and deep level transient spectroscopy. The activation energy decreases as the proportion of arsenic, y, increases. However, considering the band-edge discontinuity in this material, it was found that the Fe acceptor level is aligned at a constant energy. This is in excellent agreement with the vacuum referred binding energy model.
