For the same degree of doping, why is the conductivity of n-type semiconductor greater than that of p-type semiconductor?

Expert Answer:

The majority charge carriers are the free electrons in the n-type semiconductors whereas these are the holes in p-type semiconductor. As free electrons have more mobility than holes, therefore, n-type semiconductor has higher conductivity than that of p-type semiconductor. As a matter of fact, the conductivity of n-type semiconductor is approximately twice that of p-type semiconductor.
