title: Synthesis and metallic probe induced conductance of Au tipped ultranarrow PbS rods.
abstract: Au tipped ultranarrow PbS nanorods are synthesized. DFT electronic structure calculations and transport studies show that Au probes modify the nature and energies of PbS nanorod orbitals creating efficient electron conduction channels for enhanced conductance even at low applied bias.
