High-resolution scanning tunneling spectroscopy on rhombohedral multilayer graphene

Rhombohedral multilayer graphene has recently emerged as a natural crystalline platform for exploring a wide range of correlated and topological quantum phenomena, from unconventional superconductivity to fractional quantum anomalous Hall phases. Yet, the microscopic origins and interplay of these phases remain largely unexplored. Here, we perform scanning tunneling microscopy/spectroscopy (STM/STS) measurements on high-quality, naturally stacked rhombohedral multilayer graphene at millikelvin temperatures. STM can reveal electronic structures and energy scales at both the atomic and moiré length scales, offering new insights into the correlated and topological landscape of this system.
