Spectroscopy of the fractal Hofstadter energy spectrum
Nature, Published online: 26 February 2025; doi:10.1038/s41586-024-08550-2High-resolution STM/STS visualizes the fractionalization of flat moiré bands into discrete Hofstadter subbands in moiré graphene near the predicted second magic angle, and experimentally establishes several fundamental properties of the fractal Hofstadter energy spectrum.
