Researchers produce large regions of uniform rhombohedral four-layer graphene by introducing a small twist between two layers of bilayer graphene. Four-layer rhombohedral graphene is a new platform for realizing flat-band-based quantum phenomena in a natural way.

Scientists pioneer an approach called self-referenced streaking, clocking Auger electrons with sub-femtosecond resolution. The breakthrough will unlock the broader potential for attosecond time resolution at X-ray free-electron lasers. more
Researchers develop a groundbreaking method, Moiré metrology, to map the interaction of ultrathin layers. Information about the layers' interaction is imprinted on top of fine spatial patterns that emerge after the atomic relaxation.

Molecular quantum switches get help from the surfaces they are adsorbed on. In porphycene molecules, heavy surface atoms like copper participate in the intramolecular hydrogen tunneling reaction and can cause an increase in the tunneling rate by up to two orders of magnitude at a temperature of around 80 K.
