NONLINEAR RESPONSE OF ALUMINUM SURFACE TO ELECTRIC-FIELD

The static limit of the perpendicular second-harmonic response of the exposed single-crystal planes of aluminum to applied electric field is studied using the variant of stabilized-jellium model which allows to account for the anisotropy of surface potential. The self-consistentl y calculated linear and second-order induced charge density distributi ons are used to determine the normal component of the polarization vec tor. The surface structure is found to have a pronounced effect on the anisotropy of second-harmonic response. (C) 1997 John Wiley & Sons, I nc.
