Integrated Electronics on Aluminum Nitride

Dr. Reet Chaudhuri is a Logic Device Engineer at the Intel Corporation, where he uses semiconductor device physics for developing next-generation semiconductor transistors to keep Moore’s Law alive. Reet earned his Ph.D. in 2021 in semiconductor device physics at Cornell University, USA under the guidance of Prof Debdeep Jena, working at the intersection of solid-state physics, electronics and materials science. His doctoral research work focused on enabling integrated high-frequency electronics on the aluminum nitride (AlN) platform through careful material growth and electronic device development. His scientific discovery of the long-missing undoped mobile holes in gallium nitride in 2019 led to new insights into wide bandgap semiconductor physics, and enabled record high speed transistors crucial for future, energy-efficient electronics. During the course of his PhD, Reet has co-authored 20+ journal papers, 20+ conference presentations, 6 invited talks and 4 patents; including high impact works in Science and IEEE IEDM. He also has also co-founded a semiconductor start-up venture Soctera Inc. commercializing his research work on high-frequency signal amplifiers using aluminum nitride.
