a: Semiconductor ~
b: an insulator

What: "A semiconductor is like an insulator except that the energy required to free some electrons is not quite so great. The process of doping can supply electrons or positive charge carriers that are very loosely held within the material and thus are easy to get moving. Also, by controlling the doping of a semiconductor, one can control the density of charge carriers that are responsible for a current."
