About the Speaker
Prof 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, 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
characterisation of LETs. He joined the Department of Chemistry at The University of Hong
Kong in 2004 and he focused on various molecular materials (with Prof. Chi-Ming Che and
his group) for electronic device applications. Currently, he is an Assistant Professor in City
University of Hong Kong.
His research interests includes Molecular electronics, Molecular self-assembly, NanoPhotonics, Nano-materials science, Bio-electronics, Renewable energy (Solar and Fuel
cells) and Flexible electronics. Prof Roy mainly focuses on molecular materials (Inorganic,
organic and biological molecules) for electronic devices such as Thin Film Transistors
(TFTs), Photovoltaics and LEDs (Light Emitting Diodes). His research is interdisciplinary and
it’s a blend of Physics, Materials science, Engineering, and Biology.
Abstract
The search for new classes of organic and metal-organic compounds is of immense current
interest due to their relative low-cost and potential applications in electronic logic circuits,
photonics and in energy harvesting. The development of functional self-assembly materials
represents a new frontier in electronics with unprecedented device properties. Structural
tailorability and multifunctionality of molecules is an important criterion to develop selfassembly molecules for the incorporation in electronic switches, photovoltaic and optoelectronic devices. In this talk, I discuss various self-assembled organic/organo-metallic
molecular materials and their molecular alignment for the construction of electronic and
opto-electronic devices.
