Phonon modes in carbon nanotubules
TL;DR: In this paper, the relationship between the phonon modes in carbon nanotubules and those in a graphene sheet is studied by use of the zonefolding method, and the modes identified with pure translations and rotations are identified.

Contact Chemistry and Single-Molecule Conductance : A Comparison of Phosphines, Methyl Sulfides, and Amines
Young S. Park,Adam C. Whalley,Maria Kamenetska,Michael L. Steigerwald,Mark S. Hybertsen,Colin Nuckolls,Latha Venkataraman +6 more
TL;DR: It is found that junctions formed with dimethyl phosphine terminated alkanes have the highest conductance and this allows a detailed analysis of the single-molecule junction elongation properties which correlate well with calculations based on density functional theory.

Single-molecule diodes with high rectification ratios through environmental control
Brian Capozzi,Jianlong Xia,Olgun Adak,Emma J. Dell,Zhen-Fei Liu,Jeffrey C. Taylor,Jeffrey B. Neaton,Luis M. Campos,Latha Venkataraman +8 more
TL;DR: This method reliably and reproducibly achieve rectification ratios in excess of 200 at voltages as low as 370 mV using a symmetric oligomer of thiophene-1,1-dioxide and provides a general route for tuning nonlinear nanoscale device phenomena.

Probing the conductance superposition law in single-molecule circuits with parallel paths
Héctor Vázquez,Rachid Skouta,Severin T. Schneebeli,Maria Kamenetska,Maria Kamenetska,Ronald Breslow,Latha Venkataraman,Mark S. Hybertsen +7 more
TL;DR: Single-molecule conductance measurements and transport calculations based on density functional theory show that the conductance of a double-backbone molecular junction can be more than twice that of a single- backbone junction, providing clear evidence for constructive interference.
Amine-Gold Linked Single-Molecule Junctions: Experiment and Theory

TL;DR: In this paper, the authors measured conductance distribution for single molecule benzenediamine-gold junctions, based on 59,000 individual conductance traces recorded while breaking a gold point contact in solution, has a clear peak at 0.0064 G$_{0}$ with a width of 40%.
