One-Step Epitaxial Access to Rhombohedral Graphene Flat-Band States on Step-Bunched SiC
Hao Zhong, Xingzhe Wang, Hanbin Deng +15
Rhombohedral graphene multilayers provide a moiré-free platform for correlated and topological flat-band physics, but direct, transfer-free epitaxial access to thickness-tunable m…
Observation of quasi-steady dark excitons and gap phase in a doped semiconductor
Shangkun Mo, Yunfei Bai, Chunlong Wu +16
Exciton plays an important role in optics and optics-related behaviors and leads to novel correlated phases like charge order, exciton insulator, and exciton-polariton condensation…
Sensitive infrared surface photovoltage in quasi-equilibrium in a layered semiconductor at low-intensity low-temperature condition
Qiang Wan, Keming Zhao, Guohao Dong +10
Benefit to layer-dependent bandgap, van der Waals materials with surface photovoltaic effect (SPV) enable photodetection over a tunable wavelength range with low power consumption.…
Quantum simulation of honeycomb lattice model by high-order moiré pattern
Qiang Wan, Chunlong Wu, Xun-Jiang Luo +11
Moiré superlattices have become an emergent solid-state platform for simulating quantum lattice models. However, in single moiré device, Hamiltonians parameters like lattice cons…
