Nonlinear charge transport in bipolar semiconductors due to electron heating [PDF]
Physics Letters A, 2016 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.
