Suppose that pure silicon is doped with antimony such that one silicon atom in a billion is replaced by a Sb atom Is this an n type or p type semiconductor By what factor is the density of conduction electrons increased The intrinsic density of conduction electrons in silicon is about 10 6 m at room temperature Estimate the room temperature conductivity of this material assuming the electron and hole mobilities are the same as for the intrinsic material The conductivity of silicon at room temperature is 1 6x10 mho m By comparison the conductivity of copper is about 6x107mho m
