摘要：

A new method is used to investigate the Stark effect in solids by means of a Green's function formalism. An original and exact condition is obtained for the energy levels in a solid in the presence of an electric field of arbitrary strength, which connects these levels with the lattice parameters, electric field, and periodic potential. Unlike the usual approximate theory of the Stark effect in solids the result predicts that (depending on the values of the parameters) Stark ladders may only exist for limited ranges of energy, or not exist at all. © 1969.
