A semiconducting material that performed a quantum "flip" from a conductor to an insulator above room temperature has been developed at the University of Michigan (U-M). It potentially brings the world closer to a new generation of quantum devices and ultra-efficient electronics.
Observed in two-dimensional layers of tantalum sulfide only a single atom thick, the exotic electronic structure that supported this quantum flip was previously only stable at ultra-cold temperatures of -100 degrees Fahrenheit. The new material remains stable at up to 170 F.
"We've opened up a new playground for the future of electronic and quantum materials," said Robert Hovden, U-M assistant professor of materials science and engineering and corresponding author of the study in Nature Communications. "It represents a whole new way to access exotic states."
