Abstract

Localized thermal gradient mapping of the external quantum efficiency of a silicon photodiode is presented as the photodiode ambient temperature is set at: 28, 38, 48 and 58°C. High discrimination of the three regions: (1) the region where the p-type overlays the n-type semiconductor, (2) the region of pure n-type semiconductor, and (3) the metallic region, was realized based on the obtained thermal maps. Imaging is undertaken using a custom-built Simultaneous Optical-Feedback Confocal and Optical Beam-Induced Current (SOFCOBIC) Microscope.
