Question

a pn junction is formed in a semiconductor whenever p-doped material and n-doped material come into contact. select one: true false

Explanation:

A pn - junction is indeed formed when p - doped (with acceptor impurities, creating holes as majority carriers) and n - doped (with donor impurities, creating free electrons as majority carriers) semiconductor materials come into contact. This is a fundamental concept in semiconductor physics. The interface between the two regions (p and n) forms the pn - junction, which has important electrical properties like rectification.

Answer:

True
