Searching for superconductors – materials with zero resistivity – with the critical temperature approaching room temperature is one of the holy grails of science, with massive potential for transforming fundamental science, applied science, and society.
Researchers at the Technical University of Denmark discovered that single WSe2 crystals exhibit clear signatures of correlated tunnelling of excitons, a precursor for exciton superfluidity – and supercurrents – at room temperature. This could pave the way for the development of room-temperature devices with superconductivity-like behavior.
