Nanowerk  February 4, 2019 Researchers at UC Riverside constructed an ultrathin sandwich of the semiconductor molybdenum ditelluride between layers of graphene and bombarded the material with superfast laser pulses. They detected evidence of condensation into the equivalent of a liquid. As they turned up the amount of energy being dumped into the system, they saw the formation of an ‘anomalous photocurrent ring’ in the material. It grew like a droplet, rather than behaving like a gas. The research opens a pathway for development of practical and efficient devices to generate and detect light at terahertz wavelengths. Such devices could be […]
