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…
Flat bands and temperature-driven phase transition in quasi-one-dimensional zigzag chains
Jisong Gao, Haijun Cao, Xuegao Hu +12
Flat-band materials have garnered extensive attention due to their captivating properties associated with strong correlation effects. While flat bands have been discovered in sever…
Evidence for Two-dimensional Weyl Fermions in Air-Stable Monolayer PtTe
Zhihao Cai, Haijun Cao, Haohao Sheng +14
The Weyl semimetals represent a distinct category of topological materials wherein the low-energy excitations appear as the long-sought Weyl fermions. Exotic transport and optical…
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…
Evidence for Multiferroicity in Single-Layer CuCrSe
Zhenyu Sun, Yueqi Su, Aomiao Zhi +13
Multiferroic materials, which simultaneously exhibit ferroelectricity and magnetism, have attracted substantial attention due to their fascinating physical properties and potential…
Layer-dependent Raman spectroscopy of ultrathin TaPdTe
Zhenyu Sun, Zhaopeng Guo, Dayu Yan +7
Two-dimensional topological insulators (2DTIs) or quantum spin Hall insulators are attracting increasing attention due to their potential applications in next-generation spintronic…
