Artist’s rendition of a newly discovered superhighway for electrons that can occur in rhombohedral graphene. “We found a goldmine, and every scoop is revealing something new,” says MIT Assistant Professor Long Ju. Credit: Sampson Wilcox/Research Laboratory of Electronics, creating a five-lane electron superhighway that allows for ultra-efficient electron movement without energy loss.
“This discovery has direct implications for low-power electronic devices because no energy is lost during the propagation of electrons, which is not the case in regular materials where the electrons are scattered,” says Long Ju, an assistant professor in the Department of Physics and corresponding author of theThe phenomenon is akin to cars traveling down an open expressway as opposed to those moving through neighborhoods.
Additional co-first authors of the paper who contributed equally to the work are Zhengguang Lu and Yuxuan Yao. Lu is a postdoc in the Materials Research Laboratory. Yao conducted the work as a visiting undergraduate student from Tsinghua University.
