Twist-Controlled Modulation of Quantum Emitters in a Van der Waals Bilayer
Angus Gale, Seungjun Lee, Seungmin Park +7
Stacking and twisting two dimensional materials has garnered enormous attention across the condensed matter and the nanophotonic communities. The surge of interest stems from the e…
Emergence of unconventional magnetic order in strain-engineered RuO2/TiO2 superlattices
Seung Gyo Jeong, Seungjun Lee, Jin Young Oh +8
The spin ordering in RuO2 remains a highly debated topic, owing to its elusive nature, with reports ranging from a nonmagnetic ground state to signatures of unconventional magnetic…
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…
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…
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…
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…
