| Abstract: | In the tight binding approximation applied to a non-degenerate band, we show that the kink local density of states does neither depend on the surface nor on the step type, but only on the bulk crystal structure. This result is not valid for the kink local density of states of each atomic orbital of a degenerate band like the transition metal d band. Nevertheless, the total local densities of states for different kinks are very close to each other and also only depend on the crystal structure. |
