La meilleure recherche AFM

  • Recherchez l'AFM à un prix compétitif
  • Système intégré avec un faible encombrement
  • 33 modes et fonctions
  • Manipulation facile
Le CoreAFM est le résultat de la combinaison intelligente des composants de base de l'AFM pour atteindre une polyvalence et une convivialité maximales. En raison de cette approche de conception fondamentale, le CoreAFM est équipé pour réaliser l'AFM au mieux. La fusion d'un scanner moderne guidé par flexion, d'une platine d'échantillonnage XYZ, d'une caméra, d'une table d'isolation antivibratoire active et d'un blindage du flux d'air dans une seule unité tout-en-un donne un système AFM complet avec une empreinte compacte inégalée. Le système est livré avec un contrôleur 24 bits entièrement numérique développé spécifiquement pour la tête de balayage CoreAFM. Toutes les fonctions essentielles de l'AFM moderne font partie intégrante du système CoreAFM ; tout ce que vous avez à faire pour mettre le CoreAFM en service est de connecter le contrôleur et de brancher l'alimentation et l'USB.

Lateral force microscopy on polystyrene-polybutadiene blend

The lateral force imaging mode was used to image local friction differences between the two polymers

Polystyrene and polybutadiene are shown to have quite different surface properties
lateral-force-1 Overlay of difference between lateral deflection in forward and backward directions on top of topography. The difference is dominated by friction forces. Polystyrene (green areas) shows a higher friction than polybutadiene.System: FlexAFM with ES2 controller Scan size: 9 µm Cantilever: PPP-CONTSCROverlay of friction on topography
lateral-force-2 Overlay of average of lateral deflection in forward and backward directions on top of topography. The average is dominated by slope variations in the sample. The steepest slope (in red) is observed close to a large inset of polystyrene. The average shows no large color difference between the polymers in flatter areas.Overlay of slope on topography

Electrochemical AFM

This report demonstrates the capability of the FlexAFM in studies of charged solid-liquid interfaces

In order to carry out electrochemical(in-situ)AFM experiments, a conductive sample was mounted in an electrochemical liquid cell and connected to a lab-build bipotentiostat. We employed Clavilier-type Au(111) single crystal bead crystal electrodes with facets of micrometer-wide terraces. As examples, we studied the lifting of the Au(111)-(pxV3)reconstruction, surface oxidation as well as the growth and dissolution of copper clusters in sulfuric acid solution. electrochemical-afm

KPFM using the Nanosurf FlexAFM

Kelvin probe force microscopy imaging

Kelvin Probe Force Microscopy (KPFM) is an extension of AFM. The technique was first published in 1991 by Nonnenmacher and coworkers. Using KPFM, images can be recorded that contain information on the local work function or local contact potential difference between tip and sample. Although all Nanite systems with an SPM S200 controller and all current Easyscan 2 AFM systems are in principle capable of performing KPFM, the FlexAFM has demonstrated best KPFM performance and is therefore the instrument of choice for this type of measurement. For a detailed description of requirements and procedures, please contact Nanosurf support.

Nanosurf - NaioSTM — STM for nanoeducation
Nanosurf – NaioSTM — STM for nanoeducation
  • Atomic resolution in minutes.
  • Extremely simple handling and reliable operation.
  • Controller and scan head integrated into a single device: just connect USB and power.
An Easy Entry into the World of Atoms The first scanning tunneling microscope (STM) was developed in 1981 by Binnig and Rohrer at the IBM Research Laboratory in Rüschlikon, Switzerland, for the first time making atoms directly visible to a small group of specialists. In 1997, Nanosurf went one step further and brought atoms to the classroom! Today, well over a thousand Nanosurf STMs play a crucial role in nanotechnology education around the globe: • Teachers appreciate the ease of use of Nanosurf STMs, allowing them to offer quick and hassle-free classroom demonstrations to their students. • Students are motivated by the rapid successes achieved when using the STMs themselves during hands-on training. • Anyone can safely handle a Nanosurf STM, since STM tips are simply cut from Pt/Ir wire without requiring etching in hazardous substances. The NaioSTM is the successor to the well-known Easyscan 2 STM and brings together scan head and controller in a single instrument for even greater ease of installation, usability, and transportability. The whole setup is very resistant to vibrations and can be used in standard classroom situations. [media-downloader media_id="837" texts="Cliquez ici pour télécharger plus de détails"]
