Surface densities of states in the tight-binding approximation

We present a summary of the main results obtained by a new method of calculating the electronic structure of solids and their surfaces in the tight-binding approximation. In addition to being able to reproduce the results of Kalkstein and Soven, we obtain the local density of states at atoms in the low index surfaces of fcc, hcp and bcc d-bands. We also include examples of the effect of surface dilation, the density of states at atoms in subsurface layers, and a very simple example of the adatom density of states.
