Welcome to Heterogeneous Integration Research Group: We are a research group in the International Centre for Materials Science (ICMS), and Chemistry and Physics of Materials Unit (CPMU) of Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bangalore INDIA, led by Dr. Bivas Saha. We believe research in basic sciences, and development of smart technologies can solve most of the important and pressing challenges of our society as well as create wealth and opportunity for all of us.

Our group is focused on the development of novel functional and artificially structured materials, understand and engineer their energy transport and conversion mechanism, and develop devices for applications in energy harvest and energy efficient electronic systems such as in thermoelectrics, plasmonics and energy efficient computing. Our vision is to drastically reduce energy consumption in electronics and optoelectronics, as well as develop highly efficient energy conversion devices, which will help our nation achieve energy security as well as address climate change.

Please feel free to browse through various aspects of our research and educational program. We hope you will find something interesting and visit us again.
