Printable Electronics

We seek to develop all types of electronic devices and components which will enable the goal of making circuits printable like documents or newspapers.

Organic LED and Lighting

Issues and innovation on replacing conventional lighting sources by better technology such as white organic light emitting diodes.

Defects, Disorder and DOS

We ask a variety of questions on the effect of localized states on electrical and optical properties, their origin and relevance to applications.

Hybrid Inorganic/Organic Devices

Can hybrid strategies of using inorganic nanostructures embedded in organic semiconductors give us better performance of electronic devices keeping the processability advantages of the latter intact ?

Yashowanta Narayan Mohapatra

Welcome To Our Group

Professor of Physics and Materials Science at IIT Kanpur

Obtained Five Year Integrated M.Sc.(Hons.) in Physics degree from Birla Institute of Technology & Science (BITS), Pilani. He received his doctoral degree from Indian Institute of Science (IISc), Bangalore, and carried on his post-doctoral work there before joining IIT Kanpur in May, 1990 with a joint appointment in the Department of Physics and Materials Science Programme. He is an experimental Condensed Matter Physicist mainly intersted in Electronic Materials, and physics of semcionductor devices.


He has served for three year term each as Head of the Physics Department(2007-2009), Head, Materials Science Programme (2004-2006), and for five years as Coordinator of Samtel Centre of Display Technologies and remains an active member of each of these academic units. In 2006, he became the first occupant of the Pradeep Sindhu Chair Professor at IIT Kanpur. Professor Mohapatra is recipient of MRS Medal of MRS Indian Chapter in 2007. Prof. Mohapatra serves on the editorial board of Journal of Nanophotonics (SPIE), and Advanced Condensed Matter Physics.


According to him, what brought him to IIT Kanpur was his quest for striking a balance between teaching and research, between physics and engineering, and between academic independence and avenues for interdisciplinary collaboration.


He is a member of Materials Research Society, American Physical Society, Society for Semiconductor Devices (SSD). Professor Mohapatra has conducted several one day tutorials on electrical characterization of advanced materials at International MRS Conferences. He has been a visiting faculty at the Pennsylvania State University, and has collaborative research interests with Department of Engineering Science and Mechanics at Penn State.


He has been a member of Board of Governors of Institute of Physics (IoP), Bhubaneswar, and Research Council of National Institute for Interdisciplinary Science and Technology (NIIST), Trivandrum.


Research Activities

Our group is interested in studying the electronic and photoelectronic properties of inorganic and organic Semiconductors keeping in view their applications in diodes, solar cells, sensors and transistors.

We are specially interested in defects, disorder and density of states in these materials, and their impact on properties relevant for applications.
