Tuning magnetic and optical properties through strain in epitaxial LaCrO3 thin films
Yogesh Sharma, Binod Paudel, Jegon Lee +7
We report on the effect of epitaxial strain on magnetic and optical properties of perovskite LaCrO3 (LCO) single crystal thin films. Epitaxial LCO thin films are grown by pulsed la…
Room Temperature Ferroelectric Ferromagnet in 1D Tetrahedral Chain Network
Kyeong Tae Kang, Chang Jae Roh, Jinyoung Lim +17
Ferroelectricity occurs in crystals with broken spatial inversion symmetry. In conventional perovskite oxides, concerted ionic displacements within a three-dimensional network of t…
Synergetic Behavior in 2D Layered Material/Complex Oxide Heterostructures
Kyeong Tae Kang, Jeongmin Park, Dongseok Suh +1
The marriage between a two-dimensional layered material (2DLM) and a complex transition metal oxide (TMO) results in a variety of physical and chemical phenomena that would not hav…
Voltage Scaling of Graphene Device on SrTiO3 Epitaxial Thin Film
Jeongmin Park, Haeyong Kang, Kyeong Tae Kang +4
Electrical transport in monolayer graphene on SrTiO3 (STO) thin film is examined in order to promote gate-voltage scaling using a high-k dielectric material. The atomically flat su…
Nature of Orbital and Spin Rashba Coupling in the Surface Bands of SrTiO3 and KTaO3
Panjin Kim, Kyeong Tae Kang, Jung Hoon Han
Tight-binding models for the recently observed surface electronic bands of SrTiO3 and KTaO3 are analyzed with a view to bringing out the relevance of momentum-space chiral angular…
Soliton Defects in One-dimensional Topological Three-band Hamiltonian
Gyungchoon Go, Kyeong Tae Kang, Jung Hoon Han
Defect formation in the one-dimensional topological three-band model is examined within both lattice and continuum models. Classic results of Jackiw-Rebbi and Rice-Mele for the sol…
