A semiconductor with an electrical conductivity of 300 (?·m)-1 at room temperature is produced by doping Group IV silicon with Group V antimony. Assume that the mobility of electrons in silicon is equal to 0.10 m2 /V·s and that the mobility of holes is equal to 0.001 m2 /V·s. You can assume that this semiconductor is in the extrinsic range of operation at this temperature.
(a) What type of semiconductor is this?
(b) What doping concentration of antimony in atoms/m3 is necessary for this electrical
conductivity?
(c) State clearly any assumptions you make in this calculation.
