Abstract

Superconductivity in the simple hexagonal phase of silicon is predicted on the basis of an electron-phonon-coupling calculation and measured experimentally up to a pressure of 25 GPa in a Bridgman-type opposed-anvil device. The highest measured superconducting transition temperature is 8.2 K at 15 GPa for the simple hexagonal phase.
