Anisotropic heat conduction of coherently transported phonons in InGaO3(ZnO)m single crystal films with superlattice structures
Hai Jun Cho, Yuzhang Wu, Youngha Kwon +4
Superlattices provide a great platform for studying coherent transportation of low-frequency phonons, which are the main issues in mastering the manipulation of heat conduction. St…
Effect of lattice distortions on the electron and thermal transport properties of transparent oxide semiconductor Ba1-xSrxSnO3 solid solution films
Hai Jun Cho, Koichi Sato, Mian Wei +2
La-doped ASnO3 (A = Ba, Sr) have great potential as advanced transparent oxide semiconductors due to their large optical bandgap and relatively high electron mobility. The bandgap…
High electrical conducting deep-ultraviolet-transparent oxide semiconductor La-doped SrSnO3 exceeding ~3000 S cm-1
Mian Wei, Anup V. Sanchela, Bin Feng +3
La-doped SrSnO3 (LSSO) is known as one of deep-ultraviolet (DUV)-transparent conducting oxides with an energy bandgap of ~4.6 eV. Since LSSO can be grown heteroepitaxially on more…
Macroscopic visualization of fast electrochemical reaction of SrCoOx oxygen sponge
Qian Yang, Hai Jun Cho, Hyoungjeen Jeen +1
Strontium cobaltite (SrCoOx) is known as a material showing fast topotactic electrochemical Redox reaction so-called oxygen sponge. Although atomic scale phenomenon of the oxidatio…
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…
Oxygen vacancy driven mobility enhancement in epitaxial La-doped BaSnO3 from vacuum annealing
Hai Jun Cho, Takaki Onozato, Mian Wei +2
Wide bandgap (~3.1 eV) La-doped BaSnO3 (LBSO) has attracted increasing attention as one of the transparent oxide semiconductors since its bulk single crystal shows a high carrier m…
