Because they are very small, when compared to bulk materials, both thin films and nanoscale clusters demonstrate much different properties then their bulk counterparts. These size-dependent effects result in unusual mechanical, optical and electrical properties that when stimulated by physical changes such as adsorption, often lead to observable changes. These measurable changes can often be utilized for the development of a sensor or detector. Dr. George has employed scanning tunneling microscopy and atomic force microscopy to obtain information about the structure, composition and electrical properties of surfaces. He also has experience in x-ray photoelectron and Auger electron spectroscopies for the characterization of the chemical composition and bonding properties of surfaces. Recent research has involved investigation of the properties of microcantilevers and investigations of fundamental molecular scale interactions between cantilever tips and surfaces.
