TLDR
A molecule containing a nitroamine redox center was used in the active self-assembled monolayer in an electronic device that exhibited negative differential resistance and an on-off peak-to-valley ratio in excess of 1000:1.Abstract:
A molecule containing a nitroamine redox center (2'-amino-4-ethynylphenyl-4'-ethynylphenyl-5'-nitro-1-benzenethiol) was used in the active self-assembled monolayer in an electronic device. Current-voltage measurements of the device exhibited negative differential resistance and an on-off peak-to-valley ratio in excess of 1000:1.read more

Measurement of Single-Molecule Resistance by Repeated Formation of Molecular Junctions
Bingqian Xu,Nongjian Tao +1 more
TL;DR: The conductance of a single molecule connected to two gold electrodes was determined by repeatedly forming thousands of gold-molecule-gold junctions using conductance histograms, which revealed well-defined peaks at integer multiples of a fundamental conductance value.

Carbon nanotube-based nonvolatile random access memory for molecular computing
TL;DR: A concept for molecular electronics exploiting carbon nanotubes as both molecular device elements and molecular wires for reading and writing information was developed and the viability of this concept is demonstrated by detailed calculations and by the experimental realization of a reversible, bistable nanotube-based bit.

TL;DR: In this paper, benzene-1,4-dithiol molecules were self-assembled onto the two facing gold electrodes of a mechanically controllable break junction to form a statically stable gold-sulfur-aryl-solfur-gold system, allowing for direct observation of charge transport through the molecules.

Nanoscale metal/self-assembled monolayer/metal heterostructures
TL;DR: In this article, a self-assembled monolayer of 4-thioacetylbiphenyl with nanoscale area was investigated and the experimental results showed that thermal emission of electrons over a barrier of 0.22 eV dominates electron injection from Ti into the organic layer while the transport for electron injection was satisfied by the formula for hopping conduction.
