My research interest is in the area of nanoscience and nanotechnology. As the name suggests, "nanotechnology" refers to the development of materials in the size range of a few nanometers and their conversion into useful technology. In order to prepare future high-performance devices based on these materials, several fundamental issues need to be considered. New methods to prepare nanomaterials must be developed which are amenable to device fabrication, appropriate experiments must be devised which will allow us to investigate the fundamental properties of these materials for exploitation in devices. In addition, there are several device processing issues which must be considered for such small structures. Addressing all of these issues requires an interdisciplinary approach. My research goal is to develop an interdisciplinary program in nanoscience and technology which will address the basic science of nanomaterials and will also explore their utilization in useful technology.
