Evidence of a two-dimensional nitrogen crystalline structure on silver surfaces
Xuegao Hu, Haijun Cao, Zhicheng Gao +11
Nitrogen, the most abundant element in Earth's atmosphere, exists as a diatomic gas under standard temperature and pressure. In the two-dimensional (2D) limit, atomically thin nitr…
1D flat bands in phosphorene nanoribbons with pentagonal nature
Shuo Sun, Jing-Yang You, Zhihao Cai +16
Materials with flat bands can serve as a promising platform to investigate strongly interacting phenomena. However, experimental realization of ideal flat bands is mostly limited t…
Realization of a two-dimensional checkerboard lattice in monolayer CuN
Xuegao Hu, Run-Wu Zhang, Da-Shuai Ma +10
Two-dimensional checkerboard lattice, the simplest line-graph lattice, has been intensively studied as a toy model, while material design and synthesis remain elusive. Here, we rep…
Observation of Gapped Dirac Cones in a Two-Dimensional Su-Schrieffer-Heeger Lattice
Daiyu Geng, Hui Zhou, Shaosheng Yue +6
The Su-Schrieffer-Heeger (SSH) model in a two-dimensional rectangular lattice features gapless or gapped Dirac cones with topological edge states along specific peripheries. While…
Experimental observation of Dirac cones in artificial graphene lattices
Shaosheng Yue, Hui Zhou, Daiyu Geng +8
Artificial lattices provide a tunable platform to realize exotic quantum devices. A well-known example is artificial graphene (AG), in which electrons are confined in honeycomb lat…
Topological electronic structure in the antiferromagnet HoSbTe
Shaosheng Yue, Yuting Qian, Meng Yang +11
Magnetic topological materials, in which the time-reversal symmetry is broken, host various exotic quantum phenomena, including the quantum anomalous Hall effect, axion insulator s…
