Researchers create ‘beautiful marriage’ of quantum enemies
Cornell scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.
Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity – in which electrical resistance vanishes completely – and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.
“This is a beautiful marriage of the two things we know, at the microscale, that give electrons the most startling quantum properties,” said Debdeep Jena, the David E. Burr Professor of Engineering in the School of Electrical and Computer Engineering and Department of Materials Science and Engineering. Jena led the research, published Feb. 19 in Science Advances, with doctoral student Phillip Dang and research associate Guru Khalsa, the paper’s senior authors.
