2D metal-dichalcogenides could make thin-film lasers

Technology update at nanotechweb.org explains how tunable optical microcavity made from 2D materials such as molybdenum disulphide might be used in future optoelectronic devices such as thin-film lasers and sensitive detectors. We have fabricated the cavity using highly reflecting mirrors that confine the light emitted by the 2D structures into a narrow line – a first for such dichalcogenide microcavities, these results were recently published in Nano Letters.
