SUMMARY
The discussion focuses on the differences between ohmic contacts and Schottky contacts in the context of fabricating photodiodes, specifically p-n junctions. Ohmic contacts are preferred for their linear current-voltage characteristics, making them ideal for signal transmission. In contrast, Schottky contacts provide rectification, which can enhance sensitivity in photodiodes. Ultimately, the choice between these contacts depends on the specific application requirements, such as the need for signal rectification versus linear conductivity.
