FLAME Research Group

About the Group
Flexible Large Area Microelectronics (FLAME) Research Group primarily focuses on futuristic semiconductor devices and their applications, such as on organic/flexible electronics, micro/nano electronics, and new semiconductor devices. More specifically, it focuses on organic field-effect/thin-film transistors (FETs/TFTs), resistive random access memory (RRAM), and sensing devices for flexible and green electronics. Demonstration of newer process technologies for reducing the impact on environment with eventual biodegradability of systems is also among one of the eventual goals. Former M.Tech./PhD students graduated from the group had been placed in companies like Intel, Samsung, Global Foundries, Apple Inc. and academic institutes depending on their interest. Group has strong linkages with many reputed institutions in India such as IISc Bangalore, IIT Delhi, IIT Bombay, IIT Roorkee, IIT Guwahati, NTU Singapore, Max Planck Institute for Solid State Research, Wuppertal University Germany, and others through student visits or interactions.
