Journal ArticleDOI
Dependence of single-molecule junction conductance on molecular conformation
Latha Venkataraman,Jennifer E. Klare,Colin Nuckolls,Mark S. Hybertsen,Michael L. Steigerwald +4 more
TL;DR: Amine link groups are used to form single-molecule junctions with more reproducible current–voltage characteristics and it is found that the conductance for the series decreases with increasing twist angle, consistent with a cosine-squared relation predicted for transport through π-conjugated biphenyl systems.
Journal ArticleDOI
Single-Molecule Circuits with Well-Defined Molecular Conductance
Latha Venkataraman,Jennifer E. Klare,Iris W. Tam,Colin Nuckolls,Mark S. Hybertsen,Michael L. Steigerwald +5 more
TL;DR: In this paper, the authors measured the conductance of amine-terminated molecules by breaking Au point contacts in a molecular solution at room temperature, and they found that the variability of the observed conductance for the diamine molecule−Au junctions is much less than the variability for diisonitrile− and dithiol−AU junctions.
Journal ArticleDOI
Single-molecule junctions beyond electronic transport
TL;DR: The emerging methods being used to interrogate multiple properties in single molecule-based devices are presented, how these measurements have advanced the understanding of the structure-function relationships in molecular junctions are detailed, and the potential for future research and applications are discussed.
Journal ArticleDOI
Mechanically controlled binary conductance switching of a single-molecule junction.
Su Ying Quek,Maria Kamenetska,Michael L. Steigerwald,Hyoung Joon Choi,Steven G. Louie,Steven G. Louie,Mark S. Hybertsen,Jeffrey B. Neaton,Latha Venkataraman +8 more
TL;DR: It is shown that 4,4'-bipyridine-gold single-molecule junctions can be reversibly switched between two conductance states through repeated junction elongation and compression, and could form the basis of a new class of mechanically activated single- molecule switches.
Journal ArticleDOI
Amine-gold linked single-molecule circuits: experiment and theory.
Su Ying Quek,Latha Venkataraman,Hyoung Joon Choi,Steven G. Louie,Mark S. Hybertsen,Jeffrey B. Neaton +5 more
TL;DR: It is shown explicitly that differences in local structure have a limited influence on conductance because the amine-Au bonding motif is well-defined and flexible, explaining the narrow distributions seen in the experiments.
