Unformatted text preview: o C. The energy for vacancy formation is 0.98 eV/atom. Furthermore, the density and atomic weight for Au are 19.32 g/cm 3 and 196.9 g/mol, respectively. 8. Give some examples of zero-dimensional, one-dimensional, two-dimensional, and three-dimensional defects in a semiconductor. 9. a) The surface energy of a single crystal depends on the crystallographic orientation with respect to the surface. Explain why this is so. b) For an FCC crystal, such as aluminum, would you expect the surface energy for a (100) plane to be greater or less than that for a (111) plane? Why?...
