Coupling between electrons and charge density wave fluctuation and its possible role in superconductivity
Yeonghoon Lee, Yeahan Sur, Sunghun Kim +12
In most of charge density wave (CDW) systems of different material classes, ranging from traditional correlated systems in low-dimension to recent topological systems with Kagome l…
Topological Fermi-arc surface state covered by floating electrons on a two-dimensional electride
Chan-young Lim, Min-Seok Kim, Dong Cheol Lim +11
Two-dimensional electrides can acquire topologically non-trivial phases due to intriguing interplay between the cationic atomic layers and anionic electron layers. However, experim…
Charge ordered phases in the hole-doped triangular Mott insulator 4Hb-TaS2
Junho Bang, Byeongin Lee, Hyungryul Yang +3
4Hb-TaS2 has been proposed to possess unconventional superconductivity with broken time reveral symmetry due to distinctive layered structure, featuring a heterojunction between a…
Origin of Distinct Insulating Domains in the Layered Charge Density Wave Material 1T-TaS2
Hyungryul Yang, Byeongin Lee, Junho Bang +4
Vertical charge order shapes the electronic properties in layered charge density wave (CDW) materials. Various stacking orders inevitably create nanoscale domains with distinct ele…
