Quantum Density Oscillations of Metal Surface (Planar Uniform-Background Model)

Abstract

The quantum density oscillations of metal surface have been calculated using the planar uniform-background model of a metal surface. The calculation is carried out with aid of the density-functional formalism of an inhomogeneous electron gas, without the use of the local density approximation. The quantum density oscillation is found to be much larger than the one of the infinite square barrier model of a metal surface.
