KollegeApply · Accepted Answer

Hole is a vacancy created when an electron leaves a covalent bond. Explanation: Concept of holes in the semiconductor: 1. When an electron is removed from a covalent bond, it leaves a vacancy behind. An electron from a neighbouring atom can move into this vacancy, leaving the neighbour with a vacancy. In this way, the vacancy formed is called a hole (or cotter) and can travel through the material and serve as an additional current carrier. 2. A hole is considered a seat of positive charge, having a magnitude of charge equal to that of an electron. 3. Holes act as a virtual charge, although there is no physical charge on them. 4. The effective mass of a hole is more than an electron. 5. The mobility of a hole is less than an electron.
