Metals work function
Web15 sep. 1992 · We have performed an ab initio study of the surface energy and the work function for six close-packed surfaces of 40 elemental metals by means of a Green’s-function technique, based on the linear-muffin-tin-orbitals method within the tight-binding and atomic-sphere approximations. WebQuestion: A certain metal having a work function of 5.4eV is illuminated with light of frequency 2.3×1015 Hz. Determine the stopping potential (in V) that is required to stop the most energetic ejected electrons. Your answer should be a number with two decimal places, do not include unit.
