Research Interest

Bio- and Molecular Electronics
The research in our group focuses on several aspects related to bio- and molecular electronics
The on going projects are
(i) Construction and characterization of molecular and bio-photonic based devices. We utilize a novel vertical molecular transistor to investigate key issues in molecular electronics. Among the ongoing research projects are: polaron formation, quantum capacitance, AC molecular transistors, molecular circuits and bio-inspired devices
 (ii)  Bio-composites. The unique properties of some natural proteins are exploited to prepare thin films bio-composites. These materials show excellent electrical, mechanical and optical properties that might be used in future for various applications
