(newelectronics: Dartford, UK) -- According to the team from the University of Southampton’s Optoelectronics Research Centre, molybdenum di-sulphide (MoS2) shares many of graphene’s favorable properties, including excellent electrical conductivity and mechanical stability.

However, unlike graphene, it is made from metal (in this case molybdenum combined with sulphur). This means that it is able to emit light, paving the way for applications such as high-performance photodetectors and next-generation light-emitting devices.

Until recently, fabrication of this new class of thin metal/sulphide materials, known as transition metal di-chalcogenides, had been difficult. This is because most techniques produce only flakes, typically just a few hundred square microns in area.
