On-Chip Terahertz Spectroscopy for Dual-Gated van der Waals Heterostructures at Cryogenic Temperatures
Junseok Seo, Zhengguang Lu, Seunghyun Park +10
Van der Waals heterostructures have emerged as a versatile platform to study correlated and topological electron physics. Spectroscopy experiments in the THz regime are crucial, si…
Displacement field-controlled fractional Chern insulators and charge density waves in a graphene/hBN moiré superlattice
Samuel H. Aronson, Tonghang Han, Zhengguang Lu +5
Rhombohedral multilayer graphene, with its flat electronic bands and concentrated Berry curvature, is a promising material for the realization of correlated topological phases of m…
Extended Quantum Anomalous Hall States in Graphene/hBN Moiré Superlattices
Zhengguang Lu, Tonghang Han, Yuxuan Yao +7
Electrons in topological flat bands can form novel topological states driven by the correlation effects. The penta-layer rhombohedral graphene/hBN moire superlattice has been shown…
