SUMMARY
The terminology for n-p type semiconductors is defined by the charge carriers present in the materials, where P-type has an excess of holes and N-type has an excess of electrons. When a junction is formed between these two types, the diffusion of holes and electrons results in the P-type side becoming negatively charged and the N-type side positively charged. This is contrary to conventional battery terminology, where the negative terminal is considered lower potential and the positive terminal higher potential. The distinction arises from the behavior of charge carriers rather than conventional voltage designations.
