The semiconductor is placed in an electric field with a strength of 75 V/cm. Most nearly, what is the drift cur- rent density produced? (A) 0.19 A/cm2 (B) 31 A/cm2 (C) 85 A/cm2 (D) 120 A/cm 3. An n-type semiconductor is doped to a concentration of 5.65 x 106 carriers/cm'. The intrinsic carrier concen- tration of the semiconductor is 1010 carriers/cm", the mobility of holes is 460 cm/V.s, and the mobility of electrons is 1260 cm?/V-s. The total drift current den- sity, J, produced in a semiconductor is equal to the semi- conductor's conductivity, o, multiplied by the electric field applied to the semiconductor, E. J = JE
