Abstract

It was first suggested by Landau(1) that an electron moving in a crystal can get trapped by its interaction with the lattice. His original work was done with the idea that the probability density of finding an electron interacting with phonons will be nonzero around a certain centered polarization, and that it will vanish beyond a certain finite length from the center. In other words, the electron becomes localized. Subsequently Rashba(2) and Toyozawa(3) advanced the theory of self-trapping of electrons and excitons in crystalline solids significantly.
