Nanowire lithography: fabricating controllable electrode gaps using Au-Ag-Au nanowires.
TLDR
G gaps with 2 microm, 100 nm and 20 nm widths are demonstrated via the above-mentioned approaches and it is observed that small gaps can be formed through annealing Au-Ag-Au nanowires at 200 degrees C in air.Abstract:
A method to fabricate nanowire electrodes possessing controllable gaps is described. The method relies on electrochemical deposition and selective chemical etching or heating to selectively remove the Ag segment of Au-Ag-Au nanowires. Because the thickness of the Ag segment directly dictates the size of the nanogap, the gap width can be easily controlled during the nanowire fabrication process. Herein, we demonstrate gaps with 2 microm, 100 nm and 20 nm widths via the above-mentioned approaches. In addition, we observed that small gaps (approximately 20 nm) can be formed through annealing Au-Ag-Au nanowires at 200 degrees C in air. Electrical contact between nanowire electrodes and contact pads is studied. Using nanowire electrodes with a 100 nm gap, we subsequently fabricate organic field effect transistors (FETs) with regioregular poly(3-hexylthiophene).read more

On-wire lithography: synthesis, encoding and biological applications
TL;DR: In the OWL protocol presented here, multisegmented nanowires are grown and a support layer is deposited on one side of each nanostructure, creating structures with gaps as small as 2 nm and disks as thin as 20 nm that can be used in electrical transport, Raman enhancement and energy conversion.

Electron transport in molecular wire junctions.
TL;DR: Molecular conductance junctions are structures in which single molecules or small groups of molecules conduct electrical current between two electrodes and there is still limited correspondence between experimental and theoretical studies of these systems.

TL;DR: Over time the conductance switching of single and bundled phenylene ethynylene oligomers isolated in matrices of alkanethiolate monolayers is tracked, concluding that the switching is a result of conformational changes in the molecules or bundles, rather than electrostatic effects of charge transfer.
