Absztrakt:
Using a tight binding model we calculate the conductance of
monovalent atomic chains for different contact geometries. The
leads connected to the chains are modelled as semi-infinite fcc
lattices with different orientations and couplings. Our aim is
twofold: To check the validity of a three-parametric conductance
formula for differently oriented leads, and to investigate the
geometry dependence of the conductance oscillations. We show
that the character of these oscillations depends strongly on the
geometry of the chain-lead coupling. (C) 2007 WILEY-VCH Verlag
