Electronic and Optical Properties of TaNiSe Monolayer: A First-principles Study
Miaomiao Guo, Yuanchang Li
The crystal structure, stability, electronic and optical properties of the TaNiSe monolayer have been investigated using first-principles calculations in combination with t…
Identifying topological excitonic insulators via bulk-edge correspondence
Hongwei Qu, Zeying Zhang, Yuanchang Li
Excitonic insulator remains elusive and there has been a lack of reliable identification methods. In this work, we demonstrate the promise of topological excitonic insulators for i…
One-Dimensional Magnetic Excitonic Insulators
Jing Liu, Hongwei Qu, Yuanchang Li
Dimensionality significantly affects exciton production and condensation. Despite the report of excitonic instability in one-dimensional materials, it remains unclear whether these…
A way to identify whether a DFT gap is from right reasons or error cancellations: The case of copper chalcogenides
Jiale Shen, Haitao Liu, Yuanchang Li
Gap opening remains elusive in copper chalcogenides (Cu, = S, Se and Te), not least because Hubbard + , hybrid functional and methods have also failed. In this…
Stable phases of freestanding monolayer TiO: The emergence of out-of-plane ferroelectricity
Xiangtian Bu, Haitao Liu, Yuanchang Li
Despite being successfully synthesized [Zhang , Nat. Mater. \textbf{20}, 1073 (2021)], the monolayer structure of stable hexagonal TiO is unknown, and it is not even…
