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…
Experimental evidences of Luttinger liquid behavior in the crossed multi-wall carbon nanotubes
Jinhee Kim, Kicheon Kang, Jeong-O Lee +5
Luttinger liquid behavior was observed in a crossed junction formed with two metallic multi-wall carbon nanotubes whose differential conductance vanished with the power of bias vol…
