Title Photoinduced superconducting nanowires in GdBa2Cu3O6.5 films Type Journal Article
Year 1998 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.
Volume 73 Issue 1 Pages 120-122
Abstract We report the fabrication of high-Tc superconducting wires by photodoping a GdBa2Cu3O6.5 thin film. An optical near-field probe was used to locally excite carriers in the system at room temperature. Trapping of the photogenerated electrons define a confining potential for the conducting holes in the CuO planes. Spatially resolved reflectance measurements show the photogenerated nanowires to be ?250 nm wide. Electron diffusion, before electron capture, is believed to be responsible for the observed width of the wires.
