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.
