Theory of superconductivity in a disordered system
Abstract
The possibility of superconductivity in a disordered system is investigated. Interest is focused on amorphous and vitreous semiconductors in which the lifetimes of free charge carriers produced by the action of light can be relatively large. As in the theory of 'dirty' superconducting metals, a system of eigenfunctions for the single-electron Hamiltonian is used. The theory is built up on the basis of the Frohlich model by using the apparatus of the two-time temperature Green's functions. The possibility of externally controlling the critical temperature by varying the intensity of light is shown.
