Also known as ABC graphite, this quantum material hosts a flat band at its surfaces, leading to the emergence of new correlated phases of matter, including the recently discovered fractional Chern insulator. A major bottleneck in the exploration of this material is the identification of samples with prefect rhombohedral or ABC stacking. Our group has used electronic Raman scattering to identifying perfect rhombohedral graphite (RG), heralding a new phase in exploring this exciting and simple flat-band correlated material. The simplicity of RG offers a unique window into understanding complex electron interactions.
