Influence of the finite deformations changing the symmetry of an initial lattice on a generation of atoms displacements waves by non-equilibrium electrons

Abstract

For the model electronic spectrum in the tight-binding approximation it is shown that the finite homogeneous deformation essentially increases the quantity of pairs of electronic states which are active in generation of atoms displacement waves. This conclusion gives additional possibilities for the explanation of features of the process of martensitic transformation.
