Application of percolation theory to the problem of hopping conductivity in disordered semiconductors
Abstract
The percolation problem which arises in calculations of hopping conductivity in disordered semiconductors is reduced to finding the critical density of couplings among centers. Precise limits are found for the critical value of the average coupling density. An approximate calculation of this critical value is then carried out with the aid of a procedure which takes into account the dependence of the average number of couplings for a given center on its energy.
