Physicists name and codify new field in nanotechnology: 'electron quantum metamaterials'

New materials are being synthesized by twisting and stacking atomically thin layers. To bring it all under one roof, physicists Nathaniel Gabor of UC Riverside, and Justin C. W. Song of Nanyang Technological University, Singapore, propose this field of research be called "electron quantum metamaterials." They have just published a perspective article in Nature Nanotechnology, in which they highlight the potential of engineering synthetic periodic arrays with feature sizes below the wavelength of an electron.
