New, stable 2D materials

Dozens of new two-dimensional materials similar to graphene are now available, thanks to research from University of Manchester scientists. These 2D crystals are capable of delivering designer materials with revolutionary new properties. The problem has been that the vast majority of these atomically thin 2D crystals are unstable in air, so react and decompose before their properties can be determined and their potential applications investigated. Writing in NanoLetters , the University of Manchester team demonstrate how tailored fabrication methods can make these previously inaccessible materials useful. By protecting the new reactive crystals with more stable 2D materials, such as graphene , via computer control in a specially designed inert gas chamber environments, these materials can be successfully isolated to a single atomic layer for the first time. Combining a range of 2D materials in thin stacks give scientists the opportunity to control the properties of the materials, which can allow 'materials-to-order' to meet the demands of industry. High-frequency electronics for satellite , and light weight batteries for mobile energy storage are just two of the application areas that could benefit from this research.
