Research managed by SUNY Polytechnic Institute, Utica, and conducted by a number of collaborating institutions, has led to findings that have been named a top ten 2016 breakthrough in physics by Physics World. The publication recently named the SUNY Poly-led Institute for Nanoelectronics Discovery and Exploration’s (INDEX) “Theme I” work on the negative refraction of electrons in graphene p-n junctions as “a top ten breakthrough.” The development supports the physics for p-n junctions in graphene, which could lead to more powerful and energy-efficient computing capabilities in the future.
“SUNY Poly’s position as a world class research institution is unmatched, and our faculty and students should be proud to be a part of that success,” said Dr. Bahgat Sammakia, Interim President of SUNY Polytechnic Institute. “It’s an incredible honor to have research managed by the talented people here at SUNY Poly recognized among the top ten physics breakthroughs of this past year, and I salute the SUNY Poly INDEX team and the researchers at partnering institutions who, collectively, enabled this fascinating research.”
As part of the research, scientists created a p-n junction, a building block of many modern day semiconductor-based electronic devices, in graphene, a two-dimensional honeycomb-shaped form of carbon that is incredibly strong and conductive. By ensuring that the p-n junction interface was smooth, the researchers minimized reflections, which enabled them to measure the negative refraction of electrons, an accomplishment that could one day form the basis of a new type of electronic switch, potentially replacing the transistor.
The research that led to the notable findings was specifically conducted at Columbia University, the University of Virginia, and Harvard University, and was managed by SUNY Poly. Cornell University, the National Institute for Materials Science in Japan, and IBM were also recognized by Physics World for their contributions.
