A hole in a p-type semiconductor is
Correct answer: C. a missing electron
- A. an excess electron
- B. a missing atom
- C. a missing electron
- D. a donor level
Explanation
In a p-type semiconductor, a hole is created when a valence electron from the semiconductor crystal lattice is excited to the conduction band, leaving behind an empty state in the valence band. This empty state behaves like a positively charged particle and is called a hole

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
