Abstract
Schottky junctions (Cu-CdS and Zn-CdS) have been formed by vacuum evaporation of Cu and Zn on to cadmium sulfide
(CdS) thin films. I-V Characteristics of these junctions have been recorded at room temperature using Keithley
Electrometer. I-V Curves of these junctions show rectifying behaviour with low forward voltage drop. The other junction
parameters such as barrier height, ideality factor, series resistance and saturation current have also been calculated, which
are in good agreement with the results obtained by other workers. The Cu-CdS and Zn-CdS junctions have also been
fabricated by screen-printing technique and electrical study has been done on these junctions to obtain the junction
parameters.
