Effect of operating temperature on performance of obliquely deposited Bi, Sb, and Bi-Sb semimetal thin film laser detectors

Obliquely deposited (70/spl deg/) 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 CO/sub 2/ laser pulses have been recorded as function of opera...

Zusammenfassung:Obliquely deposited (70/spl deg/) 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 CO/sub 2/ laser pulses have been recorded as function of operating temperature between 10/spl deg/C and 120/spl deg/C. It was found that the maximum responsivity for these detectors can be obtained at 75/spl deg/C. On the other hand, the dependence of responsivity on the width of detectors was investigated.
