Su T, Li H, Klausen R, Widawsky J, Batra A, Steigerwald M, et al.
J Am Chem Soc
. 2016 Jun;
138(24):7791-5.
PMID: 27299173
While the single-molecule conductance properties of π-conjugated and σ-conjugated systems have been well-studied, little is known regarding the conductance properties of mixed σ-π backbone wires and the factors that control...

Kim T, Darancet P, Widawsky J, Kotiuga M, Quek S, Neaton J, et al.
Nano Lett
. 2014 Jan;
14(2):794-8.
PMID: 24446585
We measure conductance and thermopower of single Au-4,4'-bipyridine-Au junctions in distinct low and high conductance binding geometries accessed by modulating the electrode separation. We use these data to determine the...

Chen W, Li H, Widawsky J, Appayee C, Venkataraman L, Breslow R
J Am Chem Soc
. 2014 Jan;
136(3):918-20.
PMID: 24397414
We have measured the conductance of single-molecule junctions created with three different molecular wires using the scanning tunneling microscope-based break-junction technique. Each wire contains one of three different cyclic five-membered...

Batra A, Darancet P, Chen Q, Meisner J, Widawsky J, Neaton J, et al.
Nano Lett
. 2013 Nov;
13(12):6233-7.
PMID: 24274757
We demonstrate a new method of achieving rectification in single molecule devices using the high-bias properties of gold-carbon bonds. Our design for molecular rectifiers uses a symmetric, conjugated molecular backbone...

Su T, Widawsky J, Li H, Klausen R, Leighton J, Steigerwald M, et al.
J Am Chem Soc
. 2013 Nov;
135(49):18331-4.
PMID: 24261548
Here we demonstrate for the first time that strained silanes couple directly to gold electrodes in break-junction conductance measurements. We find that strained silicon molecular wires terminated by alkyl sulfide...

Darancet P, Widawsky J, Choi H, Venkataraman L, Neaton J
Nano Lett
. 2012 Nov;
12(12):6250-4.
PMID: 23167709
Using self-energy-corrected density functional theory (DFT) and a coherent scattering-state approach, we explain current-voltage (IV) measurements of four pyridine-Au and amine-Au linked molecular junctions with quantitative accuracy. Parameter-free many-electron self-energy...

Klausen R, Widawsky J, Steigerwald M, Venkataraman L, Nuckolls C
J Am Chem Soc
. 2012 Feb;
134(10):4541-4.
PMID: 22352896
Bulk silicon, the bedrock of information technology, consists of the deceptively simple electronic structure of just Si-Si σ bonds. Diamond has the same lattice structure as silicon, yet the two...

PMID: 22128800
We report the first concurrent determination of conductance (G) and thermopower (S) of single-molecule junctions via direct measurement of electrical and thermoelectric currents using a scanning tunneling microscope-based break-junction technique....

133(43):17160-3.
PMID: 21939263
We measure electronic conductance through single conjugated molecules bonded to Au metal electrodes with direct Au-C covalent bonds using the scanning tunneling microscope based break-junction technique. We start with molecules...

. 2011 May;
133(22):8455-7.
PMID: 21539375
Understanding the electrical properties of semiconducting quantum dot devices have been limited due to the variability of their size/composition and the chemistry of ligand/electrode binding. Furthermore, to probe their electrical...
