Nano Materials and Nanotechnology Dr R Ramaseshan From University of Tennessee web site Forward What is Nanotechnology Variants of Nanotechnology Drawbacks What is Nanotechnology Loosely defined as Matter at dimensions roughly in the range of 1 100nm Exploitation of novel and improved properties phenomena and processes specific at the scale level discussed earlier The technology to build Nano level matter using either a bottom up b top down process What makes nanostructured materials interesting Electronics and optical applications Can be defect free electrons move ballistically Quantum confinement optical properties Mechanical Properties Small enough to be defect free thus exhibiting ideal strength Thermal Properties Can be designed to conduct substantially or worse than the bulk materials Chemical Properties Dominated by large surface to volume ratio Nanotechnologies Dry Nanotechnology which drives from surface science and physical chemistry focuses on fabrication of physical structures of inorganic materials Si C Wet
