Advances in Moiré Materials and Superconductivity

Moiré materials are formed by stacking material layers with a slight twist, leading to altered atomic arrangements and unique properties. While graphene’s superconductivity is well-known, recent findings revealed tungsten diselenide (tWSe₂) as a superconductor when twisted by 3.65 degrees. This creates flat energy bands where electrons form Cooper pairs, enabling resistance-free electricity flow. Superconductivity was observed at –272.93º C, showcasing stability and potential for applications in quantum computing. These findings expand the understanding of moiré materials and promise advancements in electronic and quantum technologies.
