Spatial response uniformity of silicon-based CdS and PbS heterojunction laser detectors

الملخص EN

This paper demonstrates the spatial response uniformity (SRU) of two types of heterojunctions (CdS, PbS / Si) laser detectors.

The spatial response nonuniformity of these heterojunctions is not significant and it is negligible in comparison with p+- n silicon photodiode.

Experimental results show that the uniformity of CdS / Si is better than that of PbS / Si heterojunction.
