Calculation of ConstantEnergy Surfaces for Copper by the KorringaKohnRostoker Method
Abstract
Constantenergy surfaces are calculated for a number of different energies using three different potential functions for copper. Each surface is specified by values for 26 066 radii in k space, the radii being calculated with the KorringaKohnRostoker bandtheory method. The Fermi surfaces obtained are used to discuss the available experimental results. Values for the electronic contribution to the lowtemperature specific heat that are not clouded by statistical errors or interpolation difficulties are calculated. The densityofstates curve for a range of energies above the d bands is calculated using the Chodorow potential. Questions concerning the convergence of the calculation are treated in detail.
