Abstract
Reconstructions of GaN(0001) and (<000(1)over bar>) surfaces are studi ed by scanning tunneling microscopy and spectroscopy, by electron diff raction, by Auger electron spectroscopy, and using first-principles th eory. Attention is focused on Ga-rich reconstructions for each surface , which are found to have a metallic character involving significant o verlap between Ga valence electrons. The electron counting rule is thu s violated for these surfaces, but they nonetheless form minimum energ y structures. (C) 1998 American Vacuum Society.
