Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young's modulus 287 GPa) and a melting point of 1287 °C. The modulus of elasticity of beryllium is approximately 50% greater than that of steel. The combination of this modulus and a relatively low density results in an unusuall… WebWe report ab initio study of the electron–phonon coupling in a free standing Beryllium monolayer. The calculations were carried out using a linear–response approach in the plane–wave pseudopotential representation. The Eliashberg spectral function a2F(x) and the electron–phonon coupling parameter k are evaluated at the Fermi level.
