Spin-orbit coupling-enhanced valley ordering of malleable bands in twisted bilayer graphene on WSe2
Saisab Bhowmik, Bhaskar Ghawri, Youngju Park +8
New phases of matter can be stabilized by a combination of diverging electronic density of states, strong interactions, and spin-orbit coupling. Recent experiments in magic-angle t…
Emergence of broken-symmetry states at half-integer band fillings in twisted bilayer graphene
Saisab Bhowmik, Bhaskar Ghawri, Nicolas Leconte +9
The dominance of Coulomb interactions over kinetic energy of electrons in narrow, non-trivial moiré bands of magic-angle twisted bilayer graphene (TBG) gives rise to a variety of c…
Catalytic effect of plasma in lowering the reduction temperature of
Jaemin Yoo, Dongkyu Lee, Jimo Lee +3
Atmospheric pressure plasma (APP) generates highly reactive species that are useful for surface activations. We demonstrate a fast regeneration of iron oxides, that are popular cat…
Exploiting symmetry-mismatch to control magnetism in a ferroelastic heterostructure
Er-Jia Guo, Ryan Desautels, Dongkyu Lee +11
In the bulk, LaCoO3 (LCO) is a paramagnet, yet in tensile strained thin films at low temperature ferromagnetism (FM) is observed, and its origin remains unresolved. Polarized neutr…
Nanoscale ferroelastic twins formed in strained LaCoO3 films
Er-Jia Guo, Ryan Desautels, David Keavney +9
The coexistence and coupling of ferroelasticity and magnetic ordering in a single material offers a great opportunity to realize novel devices with multiple tuning knobs. Complex o…
Stretching Epitaxial La0.6Sr0.4CoO3-δ for Fast Oxygen Reduction
Dongkyu Lee, Ryan Jacobs, Youngseok Jee +7
The slow kinetics of the oxygen reduction reaction (ORR) is one of the key challenges in developing high performance energy devices, such as solid oxide fuel cells. Straining a fil…
Direct Probing of Polarization Charges at the Nanoscale
Owoong Kwon, Daehee Seol, Dongkyu Lee +8
Ferroelectric materials possess spontaneous polarization that can be used for multiple applications. Owing to a long term development for reducing the sizes of devices, the prepara…
Carrier and strain tunable intrinsic magnetism in two-dimensional MAX transition metal chalcogenides
Bheema Lingam Chittari, Dongkyu Lee, Allan H. MacDonald +2
We present a density functional theory study of the carrier-density and strain dependence of magnetic order in two-dimensional (2D) MAX (M= V, Cr, Mn, Fe, Co, Ni; A= Si, Ge, Sn…
Emerging magnetism and anomalous Hall effect in iridate-manganite heterostructures
John Nichols, Xiang Gao, Shinbuhm Lee +14
Strong Coulomb repulsion and spin-orbit coupling are known to give rise to exotic physical phenomena in transition metal oxides. Initial attempts to investigate systems where both…
