Single Molecule Nanoelectrochemistry in Electrical Junctions

07-Oct-2016 | Richard J. Nichols; Simon J. Higgins, Accounts of Chemical Research, 2016

ConspectusIt is now possible to reliably measure single molecule conductance in a wide variety of environments including organic liquids, ultrahigh vacuum, water, ionic liquids, and electrolytes. The most commonly used methods deploy scanning probe microscopes, mechanically formed break ...

Plasmonic Imaging of Electrochemical Reactions of Single Nanoparticles

23-Sep-2016 | Yimin Fang; Hui Wang; Hui Yu; Xianwei Liu; Wei Wang; Hong-Yuan Chen; N. J. Tao, Accounts of Chemical Research, 2016

ConspectusElectrochemical reactions are involved in many natural phenomena, and are responsible for various applications, including energy conversion and storage, material processing and protection, and chemical detection and analysis. An electrochemical reaction is accompanied by electron ...

Dynamics of thermally induced assembling of Au nanoislands from thin Au layer on Ge(001)

14-Jun-2016 | Marek Nikiel; Benedykt R. Jany; Konrad Szajna; Dominik Wrana; Arkadiusz Janas; Rafal Kozubski; Franciszek Krok, CrystEngComm, 2016

Dynamics of the morphology changes upon post deposition annealing of a thin film of 6 ML Au deposited on (2x1) reconstructed Ge(001) surface was studied by scanning electron and scanning probe microscopes. It has been found that annealing of the initial, continuous Au layer leads to the ...

Measuring Shear‐Induced Adhesion of Gecko‐Inspired Fibrillar Arrays Using Scanning Probe Techniques

30-Jul-2013 | Yasong Li, Cheng Zhang, James H.‐W. Zhou, Carlo Menon, Byron D. Gates, Macromolecular Reaction Engineering, 2013

Abstract The natural ability of geckos and spiders to climb almost all surfaces using the compliant, nano‐structured components on their feet provides motivation for making bio‐inspired adhesives. The goal of the studies in this paper is to create an analytical technique for improving the ...

Single Defect Center Scanning Near-Field Optical Microscopy on Graphene

28-Jun-2013 | Julia Tisler; Thomas Oeckinghaus; Rainer J. Stöhr; Roman Kolesov; Rolf Reuter; Friedemann Reinhard; Jörg Wrachtrup, Nano Letters, 2013

We present a scanning-probe microscope based on an atomic-size emitter, a single nitrogen-vacancy center in a nanodiamond. We employ this tool to quantitatively map the near-field coupling between the NV center and a flake of graphene in three dimensions with nanoscale resolution. Further we ...

Scalable Patterning of One-Dimensional Dangling Bond Rows on Hydrogenated Si(001)

04-Apr-2013 | François Bianco; David R. Bowler; James H. G. Owen; Sigrun A. Köster; Maria Longobardi; Christoph Renner, ACS Nano, 2013

Silicon dangling bonds exposed on the monohydride silicon (001) (Si(001):H) surface are highly reactive, thus enabling site-selective absorption of atoms and single molecules into custom patterns designed through the controlled removal of hydrogen atoms. Current implementations of high-resolution ...

Nanographene and Graphene Edges: Electronic Structure and Nanofabrication

21-Nov-2012 | Shintaro Fujii; Toshiaki Enoki, Accounts of Chemical Research, 2012

Graphene can be referred to as an infinite polycyclic aromatic hydrocarbon (PAH) consisting of an infinite number of benzene rings fused together. However, at the nanoscale, nanographene’s properties lie in between those of bulk graphene and large PAH molecules, and its electronic properties ...

Cooling of the SPM cantilever by nonlinear mechanical frequency modulation with cavity‐induced radiation force

29-Oct-2012 | Nguyen Duy Vy, Takuya Iida, physica status solidi (c), 2012

Abstract We perform a systematic analysis of the dynamics of a scanning probe microscope (SPM) cantilever incorporating the mechanical nonlinearity by the cavity‐induced radiation force (CIRF) under the random noise depending on the ambient conditions. It has been clarified that higher ...

Kelvin Probe Force Microscopy in Nonpolar Liquids

18-Sep-2012 | Anna L. Domanski; Esha Sengupta; Karina Bley; Maria B. Untch; Stefan A. L. Weber; Katharina Landfester; Clemens K. W ..., Langmuir, 2012

Work function changes of Au were measured by Kelvin probe force microscopy (KPFM) in the nonpolar liquid decane. As a proof of principle for the measurement in liquids, we investigated the work function change of an Au substrate upon hexadecanethiol chemisorption. To relate the measured contact ...

Carbon-fiber tips for scanning probe microscopes and molecular electronics experiments

02-Sep-2012 | Gabino Rubio-Bollinger, Andres Castellanos-Gomez, Stefan Bilan, Linda A Zotti, Carlos R Arroyo, Nicolás Agraït, Juan ..., Nanoscale Research Letters, 2012

We fabricate and characterize carbon-fiber tips for their use in combined scanning tunneling and force microscopy based on piezoelectric quartz tuning fork force sensors. An electrochemical fabrication procedure to etch the tips is used to yield reproducible sub-100-nm apex. We also study ...
