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…

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…
