Explain the term- Zener Breakdown
Under a very high reverse voltage, depletion region expands and potential barrier increases resulting in a very high electric field (3X107 V/m) across the junction. Electric field would break some of the covalent bonds of semiconductor reverse current. This is known as Zener effect. Breakdown occurs at a particular and constant value of reverse voltage known as the breakdown voltage.
The average distance of an electron in an atom from its nucleus is of the order of: (1) 10 6 m (2) 10 -6 m (3) 10 -10 m (4)10 -15 m Ans: (3) 10 -10 m
