Primary Investigator

Supratik Guha

Supratik Guha is a materials scientist whose research is on new semiconductors and oxide materials and devices for new computing architectures, cyberphysical sensing systems, and energy conversion technologies.  He is particularly interested in the discovery of thin film materials and novel devices that can be used for ultra-low power non Boolean computing and sensing; and believes in a top down, system level perspective for the need for specific materials and devices.

Supratik pioneered the materials research that led to IBM’s high-k dielectric metal gate transistor technology, one of the most significant developments in silicon CMOS technology in decades.  The processor chips in over fifty percent of smart phones and tablets sold today use nanoscale dielectrics and processes developed by Supratik.  He has also worked extensively on earth abundant thin film photovoltaics, and his research group has been responsible for demonstrating the highest efficiency vacuum deposited Cu2ZnSn(S,Se)4 solar cells, and the first tandem chalcogenide/perovskite solar cells to date. More recently his activities have included sensor-based analytics for geo-spatial applications such as high-resolution agriculture and the tracking of pollutants in rivers. As a manager at IBM he has had significant experience developing inter-company joint R&D alliances and has initiated or expanded several successful programs such as silicon photonics, quantum computing, carbon electronics, photovoltaics, and sensor based analytics.
