My research focuses on development of novel material systems and processes for development of functional nanomaterials. Our studies are focused on advancement of fundamental knowledge of electronic structures, carrier dynamics, and interactions between incident electromagnetic radiation and these nanoscale materials. Based on our understanding, we design and fabricate these nanostructured materials using a variety of top-down and bottom-up scalable nanofabrication techniques. We also employ a variety of spectroscopic methods including optical, electronic, ultrafast and other optoelectronic and surface sensitive spectroscopy techniques to study fundamental interaction between light, charge carriers and phonons in individual nanoparticles and mesoscale nanoparticle assemblies. This leads us to design principles for development of useful devices based on desired engineered nanoparticle properties and cooperative phenomenon in nanostructured assemblies.
