Strain Engineering of Altermagnetic Symmetry in Epitaxial RuO Films
Johnathas D. S. Forte, Seung Gyo Jeong, Anand Santhosh +3
The magnetic ground state of RuO has been under intense debate. Using first-principles calculations, we show that compressive strain along [001] direction stabilizes an alterma…
Observation of mirror-odd and mirror-even spin texture in ultrathin epitaxially strained RuO2 films
Yichen Zhang, Seung Gyo Jeong, Luca Buiarelli +24
Recently, rutile ruthenium dioxide (RuO) has attracted renewed interest due to expectations of prominent altermagnetic spin splitting. However, accumulating experimental eviden…
Strain-Stabilized Interfacial Polarization Tunes Work Function Over 1 eV in RuO2/TiO2 Heterostructures
Seung Gyo Jeong, Bonnie Y. X. Lin, Mengru Jin +14
Interfacial polarization-charge accumulation at the heterointerface-is a well-established tool in semiconductors, but its influence in metals remains unexplored. Here, we demonstra…
Moiré Collapse and Luttinger Liquids In Twisted Anisotropic Homobilayers
D. J. P. de Sousa, Seungjun Lee, Francisco Guinea +1
We introduce twisted anisotropic homobilayers as a distinct class of moiré systems, characterized by a distinctive ``magic angle", , where both the moiré unit cell and Brillou…
Generalized energy band alignment model for van der Waals heterostructures with a charge spillage dipole
Seungjun Lee, Eng Hock Lee, Young-Kyun Kwon +5
The energy band alignment at the interface of van der Waals heterostructures (vdWHs) is a key design parameter for next-generation electronic and optoelectronic devices. Although t…
Emergent superconductivity and non-reciprocal transport in a van der Waals Dirac semimetal/antiferromagnet heterostructure
Saurav Islam, Max Stanley, Anthony Richardella +6
We investigate emergent superconductivity and non-reciprocal transport (magnetochiral anisotropy, superconducting diode effect) at the heterointerface of two non-superconducting va…
Computational search for materials having a giant anomalous Hall effect in the pyrochlore and spinel crystal structures
Sean Sullivan, Seungjun Lee, Nathan J. Szymanski +4
Ferromagnetic pyrochlore and spinel materials with topological flat bands are of interest for their potential to exhibit a giant anomalous Hall effect (AHE). In this work, we prese…
Metallicity and Anomalous Hall Effect in Epitaxially-Strained, Atomically-thin RuO2 Films
Seung Gyo Jeong, Seungjun Lee, Bonnie Lin +14
The anomalous Hall effect (AHE), a hallmark of time-reversal symmetry breaking, has been reported in rutile RuO2, a debated metallic altermagnetic candidate. Previously, AHE in RuO…
