Electronic Structure, Electron-Lattice Interaction and Lattice Dynamics in fcc Solid Bromine.

Abstract

First-principles calculations are performed for electronic structure, electron-lattice inteeaction and lattice dynamics of fcc solid bromine under high pressures, and the pressure dependence of superconducting transition temperature Tc is calculated. Many aspects of the obtained results are similar to those of fcc solid iodine, and in particular Tc decreases with increasing pressure.
