1.	Define a hole. State its characteristics.
Answer» Hole is a seat of positive charge which is produced when an electron breaks away from a covalent bond in a semiconductor. Characteristics of a hole 1. Hole carries a unit positive charge. 2. It has the same magnitude of charge as that of electron. 3. Energy of a hole is high as compared to that of electron. 4. The mobility of hole is smaller than that of electron. 5. In external electric field holes move in a direction opposite to that of electron.
