Density functional theory analysis of hexagonal close-packed elemental metal photocathodes
A density function theory based analysis of photoemission from hexagonal close packed (hcp) metals is presented and the calculated values of the rms transverse momentum (Δp_{T}) are in good agreement with the available experimental data on Be [Phys. Rev. Lett. 111, 237401 (2013)] and Mg [Proceedings...
