ResumoWe present calculations of the surface electronic state dispersion curves E(k̄) of the (100) (2×1) reconstructed surface of Ge, and compare them with recent angle-resolved photoelectron measurements by Nelson et al. We assumed Chadi’s asymmetric dimer model of the surface reconstruction and performed our calculations using the analytic Green’s function technique, with an empirical tight-binding Hamiltonian.
