Application of Machine Learning to Sporadic Experimental Data for Understanding Epitaxial Strain Relaxation
Jin Young Oh, Dongwon Shin, Woo Seok Choi
Understanding epitaxial strain relaxation is one of the key challenges in functional thin films with strong structure-property relation. Herein, we employ an emerging data analytic…
Atomic and Electronic Structures of Correlated SrRuO3/SrTiO3 Superlattices
Seung Gyo Jeong, Ahmed Yousef Mohamed, Deok-Yong Cho +1
Atomic-scale precision epitaxy of perovskite oxide superlattices provides unique opportunities for controlling the correlated electronic structures, activating effective control kn…
Tunable Ferromagnetism in LaCoO3 Epitaxial Thin Films
Dongwon Shin, Sangmoon Yoon, Sehwan Song +3
Ferromagnetic insulators play a crucial role in the development of low-dissipation quantum magnetic devices for spintronics. Epitaxial LaCoO3 thin film is a prominent ferromagnetic…
Atomistic Engineering of Phonons in Functional Oxide Heterostructures
Seung Gyo Jeong, Ambrose Seo, Woo Seok Choi
Engineering of phonons, i.e., collective lattice vibrations in crystals, is essential for manipulating physical properties of materials such as thermal transport, electron-phonon i…
Defect engineering of magnetic ground state in EuTiO epitaxial thin films
Dongwon Shin, Inseo Kim, Sehwan Song +5
Atomistic defect engineering through the pulsed laser epitaxy of perovskite transition metal oxides offers facile control of their emergent opto-electromagnetic and energy properti…
Epitaxial stabilization of metastable 3C BaRuO3 thin film with ferromagnetic non-Fermi liquid phase
Sang A Lee, Jong Mok Ok, Jegon Lee +8
Thin films of perovskite Ruthenates of the general formula ARuO3 (A = Ca and Sr) are versatile electrical conductors for viable oxide electronics. They are also scientifically intr…
