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…
Tuning of altermagnetism by strain
M. Khodas, Sai Mu, I. I. Mazin +1
For all collinear altermagnets, we sort out piezomagnetic free-energy invariants allowed in the nonrelativistic limit and relativistic piezomagnetic invariants bilinear in the Née…
Optical switching of ferro-rotational charge-density wave states
Wayne Cheng-Wei Huang, Sai Mu, Gevin von Witte +7
Tailored optical excitations can steer a system along non-equilibrium pathways to metastable states with specific structural or electronic properties. The light-induced hidden stat…
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…
Intrinsic defects and 4d/5d transition metal defects in CrO: pathways to enhance the Néel temperature
Xuecong Wang, Sai Mu
First-principles calculations are employed to explore avenues to increase the Néel temperature () of the magnetoelectric antiferromagnet CrO through doping…
