Heavily doped semiconductor

A very heavily doped semiconductor behaves more like a good conductor (metal) and thus exhibits more linear positive thermal coefficient. Such effect is used for instance in sensistors. Lower dosage of doping is used in other types (NTC or PTC) thermistors.

Carrier concentration In general, increased doping leads to increased conductivity due to the higher concentration of carriers. Degenerate (very highly doped ) semiconductors have conductivity levels comparable to metals and are often used in integrated circuits as a replacement for metal.
