Nonlinear optical responses of semiconducting graphene nanoribbons: Strong constraint from a hidden symmetry
Jiawei Ruan, Weichen Tang, Yang-Hao Chan +3
Nonlinear optical (NLO) responses are powerful tools for probing material structures, as they are highly sensitive to spatial symmetries. For instance, it is well known that having…
Quantum Theory of Exciton Magnetic Moment: Interaction and Topological Effects
Gurjyot Sethi, Jiawei Ruan, Fang Zhang +4
Combining magnetometry with optical spectroscopy has uncovered novel quantum phenomena and is emerging as a powerful probe of quantum materials. However, the theory of the magnetic…
Jahn-Teller-like Distortion in a One-dimensional π-Conjugated Polymer
Ziyi Wang, Boyu Qie, Weichen Tang +8
Structurally distorting low-dimensional π-conjugated systems can profoundly influence their electronic properties, but controlling such behavior in extended-width systems remains c…
Janus graphene nanoribbons with a single ferromagnetic zigzag edge
Shaotang Song, Yu Teng, Weichen Tang +9
Topological design of pi-electrons in zigzag-edged graphene nanoribbons (ZGNRs) leads to a wealth of magnetic quantum phenomena and exotic quantum phases. Symmetric ZGNRs typically…
Regioselective On-Surface Synthesis of [3]Triangulene Graphene Nanoribbons
Michael C. Daugherty, Peter H. Jacobse, Jingwei Jiang +9
The integration of low-energy states into bottom-up engineered graphene nanoribbons (GNRs) is a robust strategy for realizing materials with tailored electronic band structure for…
