Why is the semiconductor damaged by a strong current?
Text Solution
Verified by Experts
When a strong current is passed through a semiconductor, it heats up the semiconductor. Due to it, the large number of covalent bonds break up in semiconductor , resulting large number of charge carriers. As a result of it, the material starts behaving as a conductor. At this stage, the semiconductor losses the property of low conduction, hence it is said to be damaged.
