Abstract :
Obliquely deposited (70°) Bi, Sb, and Bi-Sb alloy thin films have been prepared by thermal resistive technique. Structural properties of these films were studied using XRD. Their resistance and voltage responsivity for Nd:YAG and CO2 laser pulses have been recorded as function of operating temperature between 10°C and 120°C. It was found that the maximum responsivity for these detectors can be obtained at 75°C. On the other hand, the dependence of responsivity on the width of detectors was investigated.
