Query: Nonlinear charge transport in bipolar semiconductors due to electron
  heating   It is known that when strong electric field is applied to a semiconductor
sample, the current voltage characteristic deviates from the linear response.
In this letter, we propose a new point of view of nonlinearity in
semiconductors which is associated with the electron temperature dependence on
the recombination rate. The heating of the charge carriers breaks the balance
between generation and recombination, giving rise to nonequilibrium charge
carriers concentration and nonlinearity.
