Interplay between superconductivity and magnetism in one-unit-cell LaAlO3 capped with SrTiO3
Yongsu Kwak, Woojoo Han, Thach D. N. Ngo +13
To form a conducting layer at the interface between the oxide insulators LaAlO3 and SrTiO3, the LaAlO3 layer on the SrTiO3 substrate must be at least four unit-cells-thick. The LaA…
Polarity-tunable magnetic tunnel junctions based on ferromagnetism at oxide heterointerfaces
Thach D. N. Ngo, Jung-Won Chang, Kyujoon Lee +8
Complex oxide systems have attracted considerable attention because of their fascinating properties, including the magnetic ordering at the conducting interface between two band in…
Quantum electronic transport of topological surface states in beta-Ag2Se nanowire
Jihwan Kim, Ahreum Hwang, Sang-Hoon Lee +8
Single-crystalline β-Ag2Se nanostructures, a new class of 3D topological insulators (TIs), were synthesized using the chemical vapor transport method. The topological surface state…
Controlled formation of high-mobility shallow electron gases in SrTiO3 single crystal
Jung-Won Chang, Joon Sung Lee, Tae Ho Lee +2
We report controlled formation of sub-100 nm-thin electron channels in SrTiO by doping with oxygen vacancies induced by Ar-ion irradiation. The conducting channels exhibit…
Hole mediated ferromagnetism in Cu-doped ZnO thin films
Abhinav Pratap Singh, B. -G. Park, Ik-Jae Lee +4
We report the successful synthesis of ZnO:Cu thin films doped with holes, resulting in room temperature ferromagnetism. Hole doping is achieved by As-diffusion from the GaAs substr…
Superconducting junction of a single-crystalline Au nanowire for an ideal Josephson device
Minkyung Jung, Hyunho Noh, Yong-Joo Doh +9
We report on the fabrication and measurements of a superconducting junction of a single-crystalline Au nanowire, connected to Al electrodes. Current-Voltage characteristic curve sh…
