SUMMARY
Connecting a p-type semiconductor to a metal conductor results in a junction that behaves similarly to a pn junction, influenced by the work function of both materials. The current flow through this p-type and metal combination is typically low due to the properties of the p-type material. The electric characteristics of the metal can be analyzed as a highly degenerated n-type semiconductor, which further affects the junction behavior. Understanding these interactions is crucial for applications involving semiconductor-metal interfaces.
