In an intrinsic semiconductor, at an ordinary temperature, the correct relation between the number of electrons '$\mathrm{n}_{\mathrm{e}}$' and number of holes '$\mathrm{n}_{\mathrm{h}}$' is
  1. $\mathrm{n}_{\mathrm{e}}>\mathrm{n}_{\mathrm{h}}$
  2. $\mathrm{n}_{\mathrm{e}}=\mathrm{n}_{\mathrm{h}}$
  3. $\mathrm{n}_{\mathrm{e}}=\mathrm{n}_{\mathrm{h}}=0$
  4. $\mathrm{n}_{\mathrm{e}} < \mathrm{n}_{\mathrm{h}}$

Solution

In an intrinsic semiconductor, at an ordinary temperature, the correct relation between the number of electrons per unit volume $n_e$ and number of holes per unit volume $n_h$ is $n_e=n_h$. /
