Mobility of electron in a semiconductor is defined as the ratio of their drift velocity to the applied electric field. If, for an n-type semiconductor, the density of electrons is \( 10^{19} \mathrm{~m}^{-3} \) and their mobility is \( 1.6 \mathrm{~m}^{2} \) (V.s) then the resistivity of the semiconductor (since it is an n-type semiconductor contribution of holes is ignored) is close to :
(1) \( 2 \Omega \mathrm{m} \)
(2) \( 4 \Omega \mathrm{m} \)
(3) \( 0.4 \Omega m \)
(4) \( 0.2 \Omega \mathrm{m} \)
