Teaching Interests

Colaborative Research Programmes Highlights

• The study of process induced defect reactions and clusters in front end processing of silicon (such as RTP, heavy ion - high dose ion implantation, hydrogenation) are being carried out in collaboration with Penn State University USA.




• A novel material - copper germanide, has been synthesized for semiconductor contact technology using Ion Beam mixing at room temperature




• Sustained efforts have been made to evaluate efficacy of producing Si-Ge alloy in bi layers and multilayers using Ion Beam Mixing.




• A laboratory for electrical measurements of thin ferroelectric films have been developed including computer controlled hysteresis loop tracer and automated C-V measurements




• Extensive studies have been made on phase formation, electrical optical properties of device quality thin ferroelectric films of lead zirconate titanate films with rare earth doping. Processing and characterization of these materials for non-volatile memories have been studied with special emphasis on role of defects in controlling electrical parameters and device degradation.

Research Interest

Core Research

Professor Mohapatra's major research interests are in physics of problems connected with development, characterization and applications of electronic and optoelectronic materials , specifically in inorganic and organic semiconductors.

His group has contributed to the understanding of localized electronic states in semiconductors for optoelectronic applications through defect engineering. He has specially developed time domain electrical spectroscopies and related techniques to study a variety of systems such as III-V semiconductors, MeV ion modified silicon, nanocrystallites embedded in amorphous silicon, and ferroelectric thin films.

Currently his group is engaged in studying optoelectronic properties of polymers and organic semiconductors with a view to understand and engineer their suitability for display, photovoltaic and large area electronic applications. He is also associated with technology development of organic semiconductors as a part of interdisciplinary group at Samtel Centre for Display Technologies at IIT Kanpur, and has been active in efforts of the group to make industry-academia interaction more meaningful. He is currently coordinating Nanotechnology Initiative with a major focus on printable electronics.
