In a p-type semiconductor, the acceptor impurity produces an energy level ______ | Shaalaa.com

A certain impurity introduces two energy levels into the band gap of an n-type semiconductor; a donor level at ET^ = EV 0.3 eV and an acceptor level at ET^- = EC - 0.5 eV.? Plot Shockley Graphs for:(i) ND = 10^16 cm^-3, NA = 0, NT = 10^15 cm^-3(ii) ND = 10^16 cm^-3, NA = 0, NT = 10^17 cm^-3? Indicate EF, n, and p on the Shockley graphs for each case.? What happens to the resistivity of the material when this impurity is introduced?Use:NT^ = (NT)/(1 exp[(EF - ET^ )/kT]); NT^- = (NT)/(1 ex
