Commercialization Scope

Commercial R& D work is now being focused on nanotechnology in order to translate the pure science discoveries into usable products. While there is extensive academic and institutional interest and activity, there is also rapidly expanding commercial activity. Significant nanotechnology research work has been undertaken in recent years at the six national Nanoscale Science and Engineering Centers, located at Columbia University (New York), Cornell University (Ithaca, NY), Rensselaer...

F16 Transmission Electron Microscopes TEMs

The TEMs support a range of applications requiring ultra-high-resolution down to sub-Angstrom levels. TEMs utilize very thin (0.5 im or less) samples illuminated by an electron beam. Images are recorded by detecting the electrons that pass through the sample (similar to what happens with the light in a slide projector). These electrons pass through a system of electromagnetic lenses and are focused as an enlarged image on a fluorescent screen, a photographic film or a digital camera....

F24 Current Sensing AFM

Current-sensing AFM CSAFM uses standard AFM contact mode along ultrasharp AFM cantilevers coated with a conducting film to simultaneously probe conductivity and topography of a sample see Fig. F.6 . By applying a voltage bias between the substrate and a conducting cantilever, a current flow is generated. This current can be used to construct a spatially resolved conductivity image, so CSAFM is often referred to as a marriage between STM and force microscopy. SCAFM has proven to be useful in...
