Non-equidistant scanning approach for millimetre-sized SPM measurements

22-May-2012 | Petr Klapetek, Miroslav Valtr, Petr Buršík, Nanoscale Research Letters, 2012

Long-range scanning probe microscope (SPM) measurements are usually extremely time consuming as many data need to be collected, and the microscope probe speed is limited. In this article, we present an adaptive measurement method for a large-area SPM. In contrast to the typically used line by ...

Tip-Enhanced Raman Spectroscopy: Near-Fields Acting on a Few Molecules

04-Apr-2012 | Bruno Pettinger; Philip Schambach; Carlos J. Villagómez; Nicola Scott, Annual Review of Physical Chemistry, 2012

Tip-enhanced Raman spectroscopy (TERS) is a very powerful variant of surface-enhanced Raman spectroscopy (SERS). In a sense, TERS overcomes most of the drawbacks of SERS but keeps its advantages, such as its high sensitivity. TERS offers the additional advantages of high spatial resolution, much ...

Scan speed control for tapping mode SPM

17-Mar-2012 | Aleksey V Meshtcheryakov, Vjacheslav V Meshtcheryakov, Nanoscale Research Letters, 2012

In order to increase the imaging speed of a scanning probe microscope in tapping mode, we propose to use a dynamic controller on 'parachuting' regions. Furthermore, we propose to use variable scan speed on 'upward step' regions, with the speed determined by the error signal of the closed-loop ...

Local Organization of Graphene Network Inside Graphene/Polymer Composites

10-Feb-2012 | Alekseev, Alexander; Chen, Delei; Tkalya, Evgeniy E.; Ghislandi, Marcos G.; Syurik, Yuliya; Ageev, Oleg; Loos, Joach ..., Advanced Functional Materials, 2012

Abstract The local electrical properties of a conductive graphene/polystyrene (PS) composite sample are studied by scanning probe microscopy (SPM) applying various methods for electrical properties investigation. We show that the conductive graphene network can be separated from electrically ...

Scanning‐Probe Microscopy: Probing Access Resistance of Solid‐State Nanopores with a Scanning‐Probe Microscope Tip (Small 3/2012)

06-Feb-2012 | Hyun, Changbae; Rollings, Ryan; Li, Jiali, Small, 2012

The image features a new apparatus that combines a scanning‐probe microscope and a solid‐state nanopore device. The pore and probe are immersed in an ionic solution where an applied bias voltage creates a current through the pore. The pore is occluded as the probe approaches it, allowing the ...

Performance characteristics of polymer photovoltaic solar cells with an additive-incorporated active layer

28-Jan-2012 | Hyomin Kim, Sunseong Ok, Hyunhee Chae, Youngson Choe, Nanoscale Research Letters, 2012

We have investigated the performance characteristics of bulk-heterojunction polymer solar cells based on poly(3-hexylthiophene-2,5-diyl) and [6,6]-phenyl C61 butyric acid methyl ester by adding 1,8-octanedithiol as a processing agent in an active layer. The effects of the additive, ...

Probing Access Resistance of Solid‐State Nanopores with a Scanning‐Probe Microscope Tip

28-Dec-2011 | Hyun, Changbae; Rollings, Ryan; Li, Jiali, Small, 2011

Abstract An apparatus that integrates solid‐state nanopore ionic current measurement with a scanning‐probe microscope is developed. When a micrometer‐scale scanning‐probe tip is near a voltage‐biased nanometer‐scale pore (10–100 nm), the tip partially blocks the flow of ions to the pore and ...

Wettability characterization of transparent MgF2 nanoparticle coatings with SiO2 binder covered with fluoroalkylsilane self-assembled monolayers

19-Aug-2011 | Tsuyoshi Murata, Junko Hieda, Nagahiro Saito, Osamu Takai, Journal of Sol-Gel Science and Technology, 2011

SiO2-added MgF2 nanoparticle coatings with various surface roughness properties were formed on silica-glass substrates from autoclaved sols prepared at 100–180 °C. The samples were exposed to fluoro-alkyl silane (FAS) vapor to give hydrophobicity. All nanoparticle samples before FAS treatment had ...

Single-Molecule Recognition of Biomolecular Interaction via Kelvin Probe Force Microscopy

04-Aug-2011 | Jinsung Park; Jaemoon Yang; Gyudo Lee; Chang Young Lee; Sungsoo Na; Sang Woo Lee; Seungjoo Haam; Yong-Min Huh; Dae S ..., ACS Nano, 2011

We report the scanning probe microscope (SPM)-based single-molecule recognition of biomolecular interactions between protein kinase and small ligands (i.e., ATP and Imatinib). In general, it is difficult to sense and detect the small ligands bound to protein kinase (at single-molecule resolution) ...

In‐situ observation and relocation method of nanomaterial samples based on microscope systems

14-Jul-2011 | Leyong Zeng; Aiguo Wu; Yazhuo Wang; Shiliu Pu; Jiandong Ding, Microscopy Research and Technique, 2011

Abstract Taking poly(lactic acid) microbubbles and purple membranes as examples, a general in situ observation and relocation method of nanomaterial samples based on microscope systems was reported. First, a four‐grade coordinate with different precisions was marked around a substrate by UV ...
