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…
Buffer layer-less fabrication of high-mobility transparent oxide semiconductor, La-doped BaSnO3
Anup V. Sanchela, Mian Wei, Joonhyuk Lee +6
Transparent oxide semiconductors (TOSs) showing both high visible transparency and high electron mobility have attracted great attention towards the realization of advanced optoele…
Large thickness dependence of the carrier mobility in a transparent oxide semiconductor, La-doped BaSnO3
Anup V. Sanchela, Mian Wei, Haruki Zensyo +6
We report herein that the carrier mobility of the 2%-La-doped BaSnO3 (LBSO) films on (001) SrTiO3 and (001) MgO substrates strongly depends on the thickness whereas it is unrelated…
Atomic-Scale Structure Relaxation, Chemistry and Charge Distribution of Dislocation Cores in SrTiO3
Peng Gao, Ryo Ishikawa, Bin Feng +3
By using the state-of-the-art microscopy and spectroscopy in aberration-corrected scanning transmission electron microscopes, we determine the atomic arrangements, occupancy, eleme…
