Experiments hint at a new type of electronics: valleytronics
Molybdenum disulphide consists of sulfur (yellow spheres) and molybdenum (blue spheres) in a staggered hexagonal structure. The links between each pair of sulfur and molybdenum atoms allow for special energy valleys, leading to a new type of electronics. Ben Mills/Wikipedia Electronics operate by exploiting the properties of the carriers of electric charge in materials, which are due to the detailed interactions between electrons and the crystal lattice formed by atoms. Conventional semiconductor electronics use the flow of electric charge, and spintronics are based on the spins of the charge...
