Biography

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.

Currently he is leading a group of Physicists, Chemists and Engineers for the fabrication of functional self-assembly materials to devices and integration of such devices for printed electronics and energy harvesting devices.
