Defect-induced displacement of topological surface state in quantum magnet MnBiTe
Felix Lüpke, Marek Kolmer, Hengxin Tan +6
The study shows that antisite defects in the magnetic topological material MnBi₂Te₄ push its topological surface state deeper into the crystal, reducing the surface gap, as demonst…

Revealing Charge Transfer in Defect-Engineered 4H-TaS
Siavash Karbasizadeh, Wooin Yang, Wonhee Ko +4
We present a comprehensive first-principles investigation of defects in 4-TaS. In this layered transition metal dichalcogenide, charge transfer between alternating Mott-in…

Nanoscale Modulation of Flat Bands via Controllable Charge-Density-Waves Defects in 4Hb-TaS2
Wooin Yang, Siavash Karbasizadeh, Hoyeon Jeon +7
Electron correlation is a main driver of exotic quantum phases and their interplay. The 4Hb-TaS2 system, possessing intrinsic heterostructure of 1T- and 1H-TaS2 monolayers, offers…
