IBM Pushes Atomic Force Microscopy to Its Limits - IEEE Spectrum

Back in 2009 IBM pushed the boundaries of surface microscopy when they developed a technique for noncontact atomic force microscopy (AFM) that enabled the resolving of single atoms in molecules. Since then IBM has been working on this foundational work to develop a Kelvin probe force microscopy (KPFM) technique that enabled the first imaging of the charge distribution within a molecule . Now the team, based in Zurich, that have been at the forefront of this research have just completed some collaborative research with the Royal Society of Chemistry (RSC) and the University of Warwick in which they have imaged the synthetic molecule Olympicene (named after its resemblance to the five-ring design of the Olympic symbol) to the point where they could not only image individual hydrogen atoms but also manipulate them. Here's a video describing the research: While IBM’s noncontac...
