SUMMARY
The discussion focuses on the formation of an ohmic contact between a metal and an n-type semiconductor, highlighting the upward bending of the energy bands in the n-type material. This bending occurs due to the accumulation of negative charge within the semiconductor, which creates an electric field that halts further electron flow from the metal. The presence of a non-zero charge density leads to the depletion of electrons from the metal and their accumulation in the semiconductor, resulting in a net negative charge.
