The relation between number of free electrons \( (\mathrm{n}) \) in a semiconductor and temperature (T) is given by
(a) \( \mathrm{n} \propto \mathrm{T} \)
(b) \( \mathrm{n} \propto \mathrm{T}^{2} \)
(c) \( \mathrm{n} \propto \sqrt{\mathrm{T}} \)
(d) \( \mathrm{n} \propto \mathrm{T}^{3 / 2} \)
\( \mathrm{P} \)
