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 $v_d=\frac{i}{\left(n_e\right)eA}$
