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…
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…
Fano resonance in crossed carbon nanotubes
Jinhee Kim, Jae-Ryoung Kim, Jeong-O Lee +6
We report the observation of the resonant transport in multiwall carbon nanotubes in a crossed geometry. The resonant transport is manifested by an asymmetric peak in the different…
