Question

If $n_{e}$ and $v_{d}$ be the number of electrons and drift velocity in a semiconductor. When the temperature is increased

• A. $n_{e}$ increases and $v_{d}$ decreases
• B. $n_{e}$ decreases and $v_{d}$ increases
• C. Both $n_{e}$ and $v_{d}$ increases
• D. Both $n_{e}$ and $v_{d}$ decreases

Answer 1

Answer: (A)

Because $v_{d}=\frac{i}{\left(n_{e}\right) e A}$
