Question

A semiconductor with equal concentration of acceptor and donor type impurities is termed as

Answer 1

Answer:

If both donors and acceptors are added to a semiconductor, they “compensate” each other, since electrons supplied by donors occupy the vacant levels in the valence band created by the acceptor atoms. In this case, the semiconductor is called compensated.

Answer 2

A semiconductor with an equal concentration of acceptor and donor type impurities is termed as compensated.

• A semiconductor "compensates" for the addition of both donors and acceptors because the electrons supplied by the donors fill the empty levels in the valence band that the acceptor atoms produce.
• The semiconductor is referred to as compensated in this instance.
• In reality, compensatory doping is quite challenging to accomplish.
• As the "free" electrons will become imprisoned in a "free" hole, they do tend to cancel one another out.
