Metals are good conductors of electricity

(C) Metals are good conductors of electricity due to the presence of free electrons. Electrical conductivity of semiconductors increases with an increase in temperature. Silicon doped with boron (Group $13$ element) creates a $p$-type semiconductor. Silicon doped with arsenic (Group $15$ element) creates an $n$-type semiconductor.
