Crystalline symmetry-dependent magnon formation in itinerant ferromagnet SrRuO3
Hyun Il Seo, Sungmin Woo, Jihyun Kim +3
SrRuO3 (SRO) is an itinerant ferromagnet with strong coupling between the charge, spin, and lattice degrees of freedom. This strong coupling suggests that the electronic and magnet…
Phase Instability amid Dimensional Crossover in Artificial Oxide Crystal
Seung Gyo Jeong, Taewon Min, Sungmin Woo +13
Artificial crystals synthesized by atomic-scale epitaxy provides the ability to control the dimensions of the quantum phases and associated phase transitions via precise thickness…
Oxygen vacancy-induced structural evolution of SrFeO epitaxial thin film from brownmillerite to perovskite
Seulki Roh, Seokbae Lee, Myounghoon Lee +8
We investigated SrFeO thin films on a SrTiO (001) substrate prepared via pulsed laser epitaxy using an optical spectroscopy technique. The oxygen vacancy level () wa…
Enhanced magnetic and thermoelectric properties in epitaxial polycrystalline SrRuO3 thin film
Sungmin Woo, Sang A Lee, Hyeona Mun +11
Transition metal oxide thin films show versatile electrical, magnetic, and thermal properties which can be tailored by deliberately introducing macroscopic grain boundaries via pol…
Enhanced electrocatalytic activity via phase transitions in strongly correlated SrRuO3 thin films
Sang A Lee, Seokjae Oh, Jae-Yeol Hwang +12
Transition metal oxides have been extensively studied and utilized as efficient catalysts. However, the strongly correlated behavior which often results in intriguing emergent phen…
Phase transitions via selective elemental vacancy engineering in complex oxide thin films
Sang A Lee, Hoidong Jeong, Sungmin Woo +9
Defect engineering has brought about a unique level of control for Si-based semiconductors, leading to the optimization of various opto-electronic properties and devices. With rega…
