Layer Number Sets the Chern Number in Twisted Rhombohedral Graphene: An Abstract-Level Reading of a Single-Device-Scale Transport Experiment
Analysis based on information available as of August 17, 2026. 30-second summary What: A Nature Materials paper (online August 14, 2026) reports electrical-transport experiments on twisted monolayer-multilayer rhombohedral graphene (1+N). In devices with N = 3, 4 and 5 layers, the authors report quantum anomalous Hall (QAH) states with Chern number C = N. They…
