On the Diffusion Theory of Rectification
TL;DR: In this article, a method of analyzing direct current-voltage curves of contact rectifiers by a uniform method which is based on both forward and reverse characteristics is proposed. But the method is not suitable for the case of a single rectifier.

F.A. Lindholm,R.W. Ayers +1 more
TL;DR: In this paper, the generalized Einstein relation holds for degenerate as well as nondegenerate semicoductors, and asymptotic and middle-range approximations are set down and are used to plot the diffusivity-mobility ratio against carrier concentration for silicon and germanium.

Influence of band tails on the diffusivity-mobility ratio in highly degenerate semiconductors
A. N. Chakravarti,D. P. Parui +1 more
TL;DR: The diffusivity-mobility ratio of the carriers in highly degenerate semiconductors in which the impurity states form band tails is shown to be directly determined by the characteristic energies of the tails at low temperatures as mentioned in this paper.
