Density of electrons in an n-type semiconductor is $10^{19} m^{-3}$. If the drift velocity is 0.02 mm/s, when an electric field $1.33 × 10^{-5}V/m$ is applied. Find the resistivity of semiconductor [contribution of holes is ignored] |
1 Ωm 2 Ωm 0.2 Ωm 0.4 Ωm |
0.4 Ωm |
The correct answer is Option (4) → 0.4 Ωm |
