A method to observe a new class of topological materials, called Weyl semimetals, was developed by researchers at Penn State, MIT, Tohoku University, Japan and the Indonesian Institute of Sciences. The material's unusual electronic properties could be useful in future electronics and in quantum physics.
"Weyl semimetals are interesting because their electron transport shows some unusual behavior," says Shengxi Huang, assistant professor of electrical engineering, Penn State. "For example, they can show negative magnetoresistance, which means when you apply a magnetic field, the resistance drops. With many conventional materials, it increases."
