This article discusses AFM studies of self-assembled semi-fluorinated alkanes on Silicon, HOPG, and MoS 2 substrates. Covalently linked sequences of -CF 2 - and -CH 2 - groups with -CF 3 and -CH 3 - ...

The origin of bond-resolved atomic force microscope images remains controversial. Moreover, most work to date has involved planar, conjugated hydrocarbon molecules on a metal substrate thereby ...

Normal alkanes C n H 2n+2 are extended linear chain molecules that form ordered lamellar structures and crystals. When the size of the chains reaches n > 120, such ultra-long alkanes manifest chain ...

The method used here of vertical interchange of atoms between tip and surface was found to be about ten times faster than previous lateral manipulations of atoms with the AFM. Using vertical ...

Scanning Electrochemical Cell Microscopy (SECCM) offers enhanced spatial resolution for visualizing electroactivity on surfaces. Highly Oriented Pyrolytic Graphite (HOPG) is a widely used substrate in ...

Distinguishing between B, C and N atoms: the AFM technique. Courtesy: S Kawai Distinguishing between B, C and N atoms: the AFM technique. Courtesy: S Kawai Atomic force microscopy can successfully be ...

Atomic force microscopy (AFM) can get chemists pretty close to actually seeing the atoms and bonds of molecules. The technique produces images a bit like a record player generates sound. An ...

(Nanowerk News) For physicist Percy Zahl, optimizing and preparing a noncontact atomic force microscope (nc-AFM) to directly visualize the chemical structure of a single molecule is a bit like playing ...

(Nanowerk Spotlight) The foremost atom of the tip in a scanning probe microscope is critically important for precise imaging results – similar to role of the objective lens in an optical microscope.
