Question

At $0\, K$ temperature, a $p$ - type semiconductor

• A. does not have any charge carriers
• B. has few holes but no free electrons
• C. has few holes and few free electrons
• D. has equal number of holes and free electrons

Answer 1

Answer: (B)

has few holes but no free electrons

Answer 2

At $0 \,K$ temperature, a pure semiconductor behaves as an insulator, because it has a few holes in its valence band. But there is no free electron in this state.
