E = V 2 = − T The … Webbv its velocity and m its mass. It should be noted that, in a general case, effective electron masses may differ in different media, but in the current study we take it equal to the free electron mass, m = me. The shape of the band of final states for the ejected electrons is taken as parabolic, setting its origin at V0. This mesoscopic
