The formation of anodic fluoride on HgMnTe has been studied and the co
mposition of the interface and the chemical depth profiles have been c
haracterized by x-ray photoelectron spectroscopy technique. Comparison
results between HgMnTe and HgCdTe were given. Metal-insulator-semicon
ductor devices containing an anodic fluoride layer and a ZnS coating w
ere fabricated and characterized. The mixture of anodic fluoride and t
hin native oxide layer may create a good interface for HgMnTe passivat
ion. (C) 1997 American Vacuum Society.
