Free Carrier Concentration

Free Carrier Concentration

Free Carrier Concentration is the concentration of free carriers in a doped semiconductior. It is similar to the carrier concentration in a metal and for the purposes of calculating currents or drift velocities can be used in the same way. It should be noted that free carriers are electrons (or holes) which have been introduced directly into the conduction (valence) band by doping and are not promoted thermally. For this reason electrons (holes) will not act as double carriers by leaving behind holes (electrons) in the other band.
