Roy started his research on light emitting materials for his PhD, mainly on ESR (Electron Spin Resonance) analysis of organic materials with Dr. R. B. Pode (Nagpur), Dr. Baldacchini (ENEA, Rome) and Dr. T. K. Gundurao (IIT, Bombay). After his PhD, he started working on the growth of wide band gap nano-structures (ZnO) and their physical (optical & magnetic) properties with the intention that they could be used in electronic devices as nano-composites. For his post-doctoral studies (with Dr. Michele Muccini and his group at ISMN, CNR di Bologna, Italy), he focused on the growth of various organic molecules for light emitting transistors (LET) and opto-electronic characterization of LETs. In 2004, he joined the Department of Chemistry at The University of Hong Kong and he focused on various molecular materials (with Prof. Chi-Ming Che and his group) for electronic device applications.
Research Interests Roy focuses on materials and technologies for sensors, memory devices and thermo-electric energy harvesting devices. He uses molecular self-assembly approach to construct layer by layer devices and adopts printing of materials for large scale fabrication and integration. He also works on the study of cell mortality under radiation.
