Conductance at the Fermi level for monoatomic gold nanowires with (a) single kink as a function of kink angle, (b) triangular kink as a function of number of atoms in the triangle, and (c) step as a function of step length for a step height of three atoms.
Transmission coefficient at zero bias for several kink angles of a monoatomic gold chain in vacuum. The solid black curve corresponds to the infinite equally spaced chain in vacuum. Gold atoms are separated by 2.9 Å. A gold chain with an angled kink is shown in Fig. 1(a).
Transmission coefficient as a function of energy for several thin pristine SiNWs.
Transmission coefficient as a function of energy for kinked SiNWs. The numbered curves correspond to  wires with  kinks of different lengths.
Conductances for several NWs. is the length of the  legs of the step along the  axis in units of the wire’s lattice constant. is the length of the top section of the step in units of the wire’s lattice constant. The conductance of the straight Al wire is . The conductance of the straight Si nanowire is along the  direction and along .
