we have investigated a new type of passivation film GdTe/ZnS for HgCdTe.With proper processing conditions
the interface electicaI properties are: the flat band voltage V

.These results show CdTe/ZnS film is superior to ZnS
and suitable for passivation of HgCdTe PV devices.We have also investigated single layer ZnS and anodic oxideICdTe/ZnS triple Iayer film. And set up a mea-surement system for MIS GV/GV characteristics
