Ritesh is developing techniques for the rational synthesis of functional nanostructural materials for applications in nanophotonic and electronic devices. His interests extend across several frontiers of science and engineering, including growth of self-assembled nanostructures, nanoscale physical behavior, and hierarchical assembly of nanostructures into integrated nanosystems. Ritesh's work includes projects with semiconductor nanowire heterostructures, interfacial phenomena, and phase-transitions at the nanoscale, and has led to the demonstration of nanowire-based injection lasers, avalanche photodiodes and phase-change electronic memory.
