Abstract

We have studied the surface state of Cu(111) using an ellipsoidal‐mirror analyzer which gives two dimensional images of photoelectron intensity versus emission angle. By combining these images, we have obtained the surface‐state dispersion in three dimensional E versus k space. We have also studied the bulk Fermi surface of Cu(100). Our results are in excellent agreement with previous studies and provide a new perspective on studies of surface electronic structure.
