Femtosecond mechanisms of electronic excitations in crystalline materials

Femtosecond mechanisms of electronic excitations in crystalline materials The lattice dynamics of crystals is investigated in the course of high-power electronic excitation.

Abstract

The lattice dynamics of crystals is investigated in the course of high-power electronic excitation. It is revealed that, at W e < W eo , atoms and ions are displaced from their regular sites for 100–300 fs. Subsequent relaxation of the crystal lattice in response to a strong local electric field induced by the collisional displacement of ions occurs for 10–50 ns in an oscillatory manner with a period of 0.5–1.5 ps.
