Good morning, Please plan on attending if your schedule allows. Thank You, Janet Werner Mathematics and Computer Science Division [email protected]<mailto:[email protected]> (630) 252-3050 Argonne Virtual Microelectronics Colloquium Speaker: Professor Debdeep Jena Affiliation: Cornell University Electrical and Computer Engineering Department Materials Science and Engineering Department Ithaca, New York Title: “Ultrawide bandgap semiconductors for microwave and power electronics and for quantum systems” Host: Anand Bhattacharya Date/Time: Friday, June 18, 2021; 1:00 PM CDT Zoom: https://argonne.zoomgov.com/j/16064119835 Abstract: The nitride semiconductors are the most revolutionary since Silicon. Though well known for visible photonics and lighting, they have much more to offer than initially imagined. The combination of polarization-induced complementary n- and p-type doping and combination of ultra-wide bandgap Aluminum Gallium Nitride quantum heterostructures with epitaxial nitride metals, nitride superconductors, and nitride ferroelectrics is leading to an exciting and unique material platform that enables applications ranging from high-speed RF communications, power electronics, and quantum communications and computation. I will discuss these opportunities and the challenges that researchers must address to achieve the promise. In this context I will share our recent findings of high-density 2-dimensional hole gases in undoped nitride semiconductor quantum heterostructures, and ferroelectricity in epitaxial nitrides, and how these findings are extending wide-bandgap electronics into unchartered application areas. Bio: Debdeep Jena [website<https://djena.engineering.cornell.edu/>] is the David E. Burr Professor at Cornell University. His teaching and research are in the quantum physics of semiconductors and electronic and photonic devices based on quantized semiconductor structures (e.g. Nitrides, Oxides, 2D Materials), and their heterostructures with superconductors, ferroelectrics and magnets, with device applications in energy-efficient transistors, light-emitting diodes and RF and power electronics and quantum computation and communications. His research is driven by the goal to enable orders of magnitude increase in the energy efficiency and speed for computation, memory, communications, lighting, and electrical energy management ranging from the chip to the grid. The research from his group has been published in more than 300 journal papers including in Science, Nature, Physical Review Letters, Applied Physics Letters and Electron Device Letters. Several patents have been granted for the group’s research work. He is a fellow of the American Physical Society and is the winner of teaching awards and research awards such as the ISCS young scientist award in 2012, MBE young scientist award in 2014, and awards from the industry such as the IBM faculty award in 2012, and most recently the Intel outstanding research award in 2021.
