False Prediction of Fundamental Properties of Metals by Hybrid Functionals
Weiwei Gao, Tesfaye A. Abtew, Tianyi Cai +3
The repercussions of an inaccurate account of electronic states near the Fermi level EF by hybrid functionals in predicting several important metallic properties are investigated.…
Magnetic control of the valley degree of freedom of massive Dirac fermions with application to transition metal dichalcogenides
Tianyi Cai, Shengyuan A. Yang, Xiao Li +4
We study the valley-dependent magnetic and transport properties of massive Dirac fermions in multivalley systems such as the transition metal dichalcogenides. The asymmetry of the…
Oxygen-Vacancy-Induced Antiferromagnetism to Ferromagnetism Transformation in Multiferroic Thin Films
Weiwei Li, Run Zhao, Le Wang +15
Oxygen vacancies (VOs) effects on magnetic ordering in Eu0.5Ba0.5TiO3-δ (EBTO3-δ) thin films have been investigated using a combination of experimental measurements and first-princ…
Anomalous Magnetic Susceptibility and Hall Effect from Valley Degrees of Freedom
Tianyi Cai, Wang Yao, Shengyuan A. Yang +2
We study the magnetic and transport properties of epitaxial graphene films in this letter. We predict enhanced signal of magnetic susceptibility and relate it to the intrinsic vall…
Interfacial Magnetoelectric Coupling in Tri-component Superlattices
Jaekwang Lee, Na Sai, Tianyi Cai +2
Using first-principles density functional theory, we investigate the interfacial magnetoelectric coupling in a tri-component superlattice composed of a ferromagnetic metal (FM), fe…
Magnetoelectric Coupling and Electric Control of Magnetization in Ferromagnet-Ferroelectric-Metal Superlattices
Tianyi Cai, Sheng Ju, Jaekwang Lee +6
Ferromagnet-ferroelectric-metal superlattices are proposed to realize the large room-temperature magnetoelectric effect. Spin dependent electron screening is the fundamental mechan…
