Selenium (Se) is a group VI element (i.e. two columns to the right of Silicon on the periodic table). An extrinsic semiconductor is produced by doping Silicon (Si) with 1020 Selenium atoms per m3. Assuming saturation, calculate the conductivity of the extrinsic semiconductor.

Question

Note: Assume that the mobility of holes is equal to $= 0.05\; m^2/(V.s)$ and that the mobility of electrons is equal to $= 0.14 \;m^2/(Vs)$
