The carrier density of a semiconductor changes with the activation temperature of the activation energy E2. A line represented by the Arrhenius plot is a straight line; but what is the change rule for doped semiconductors? Tian 1 is the electron density of the n-type semiconductor

Niusto. Please note that the abscissa of Figure 1 is 1/T, the lower the temperature to the right.

Generally speaking, semiconductors include both donors and acceptors. When the donor density N is larger than the acceptor density N, the acceptor is buried by the donor electron (this case is called compensation), N. -N is the net donor density.
