Unconventional band structure via combined molecular orbital and lattice symmetries in a surface-confined metallated graphdiyne sheet
Ignacio Piquero-Zulaica, Wenqi Hu, Ari Paavo Seitsonen +13
Graphyne (GY) and graphdiyne (GDY)-based materials represent an intriguing class of two-dimensional (2D) carbon-rich networks with tunable structures and properties surpassing thos…
Bound excitons and bandgap engineering in violet phosphorus
Zhenyu Sun, Zhihao Cai, Peng Cheng +5
Violet phosphorus (VP), the most stable phosphorus allotrope, is a van der Waals semiconductor that can be used to construct -type nanodevices. Recently, high-quality V…
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…
