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 mu…
Quasi-steady electron-excitonic complexes coupling in a two-dimensional semiconductor
Shangkun Mo, Hao Zhong, Keming Zhao +10
Excitons and their complexes govern optical-related behaviors in semiconductors. Here, using angle-resolved photoemission spectroscopy (ARPES), we have elucidated the light-matter…
Surface band-selective moiré effect induces flat band in mixed-dimensional heterostructures
Shuming Yu, Zhentao Fu, Dingkun Qin +11
In this work, we reveal a curious type of moiré effect that selectively modifies the surface states of bulk crystal. We synthesize mixed-dimensional heterostructures consisting of…
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…
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 consta…
Surface region band enhancement in noble gas adsorption assisted ARPES on kagome superconductor RbV3Sb5
Cao Peng, Yiwei Li, Xu Chen +13
Electronic states near surface regions can be distinct from bulk states, which are paramount in understanding various physical phenomena occurring at surfaces and in applications i…
Tailoring Dirac fermions by in-situ tunable high-order moire pattern in graphene-monolayer xenon heterostructure
Chunlong Wu, Qiang Wan, Cao Peng +8
A variety of novel quantum phases have been achieved in twist bilayer graphene (tBLG) and other moire superlattices recently, including correlated insulators, superconductivity, ma…
Observation of multi Dirac fermion cloning induced by moiré potential in graphene-SiC heterostructure
C. L. Wu, Q. Wan, C. Peng +6
We reexamine the electronic structure of graphene on SiC substrate by angle-resolved photoemission spectroscopy. We directly observed multiply cloning of Dirac cone, in addition to…
