Hierarchies of Hofstadter butterflies in 2D covalent organic frameworks
Abstract The Hofstadter butterfly is one of the first and most fascinating examples of the fractal and self-similar quantum nature of free electrons in a lattice pierced by a perpendicular magnetic field. However, the direct experimental verification of this effect on single-layer materials is still...
