Imaging Interacting Two-Dimensional Anisotropic Electrons
Ziyu Xiang, Jianghan Xiao, Hongyuan Li +9
We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with…
Ferromagnetic Insulator to Metal Transition in Non-Centrosymmetric Graphene Nanoribbons
Aidan P. Delgado, Michael C. Daugherty, Weichen Tang +2
Engineering sublattice imbalance within the unit cell of bottom-up synthesized graphene nanoribbons (GNRs) represents a versatile tool for realizing custom-tailored quantum nanomat…
Ab initio quantum embedding description of magic angle twisted bilayer graphene at even-integer fillings
Raehyun Kim, Woochang Kim, Kevin D. Stubbs +2
Magic angle twisted bilayer graphene (MATBG) hosts narrow moiré bands with meV-scale energy splittings, making its correlated phases sensitive to both material parameters and mode…
Engineering phase-frustration induced flat bands in an aza-triangulene covalent Kagome lattice
Yuyi Yan, Fujia Liu, Weichen Tang +4
Pi-conjugated covalent organic frameworks (COFs) provide a versatile platform for the realization of designer quantum nanomaterials. Strong electron-electron correlation within the…
Jahn-Teller-like Distortion in a One-dimensional Ï-Conjugated Polymer
Ziyi Wang, Boyu Qie, Weichen Tang +8
Structurally distorting low-dimensional Ï-conjugated systems can profoundly influence their electronic properties, but controlling such behavior in extended-width systems remains…
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…
