Near field microscopies

Near field microscopies cover a whole of techniques making it possible to visualize the surface of materials at a nanometric scale. These microscopies gather: - Scanning Tunneling Microscopy (STM) - Atomic Force Microscopy (AFM) - Magnetic Force Microscopy (MFM) All these techniques have in common the positioning nanometric of a tip on top of the sample whose position is controlled according to the selected signal (current, force).

Nanomechanical and Structural Study of Au38 Nanocluster Langmuir-Blodgett Films Using Bimodal Atomic Force Microscopy and X-Ray Reflectivity

Michal Swierczewski, Alexis Chenneviere, Lay-Theng Lee, Plinio Maroni, Thomas Bürgi Langmuir-Blodgett (LB) technique allows the deposition of gold nanoclusters (atomically precise nanoparticles below 2 nm in diameter) onto solid substrates with an unprecedented degree of control and high transfer ratios. Nanoclusters are expected to follow the crinkle folding mechanism, which promotes the formation of trilayers but kinetically disfavors the formation of the fourth layer.
