Ion-beam-assisted deposition of magnesium oxide films for coated conductors.

PDF Version Also Available for Download.

Description

The development of high critical-temperature thin-film superconductors and coated conducting wires is important for electric power applications. To achieve high transport current density, template films are necessary for the successful deposition of biaxially aligned YBa{sub 2}Cu{sub 3}O{sub 7-x} (YBCO) on flexible metal substrates. We grew biaxially aligned magnesium oxide (MgO) template films by ion-beam-assisted deposition with electron-beam evaporation. MgO films of {approx}100 {angstrom} thickness were deposited on Si{sub 3}N{sub 4}-coated Si substrates at a deposition rate of {approx}1.5 {angstrom}/sec with an ion flux of {approx}110 {micro}A/cm{sup 2} bombarding the substrate at a 45{sup o} angle. To study crystalline structure by ... continued below

To study crystalline structure by X-ray diffraction, we deposited an additional layer of MgO. Good in- and out-of-plane alignment was observed, with (111) {phi}-scan full-width half-maximum (FWHM) of 6.2{sup o} and (002) {omega}-scan FWHM of 2.2{sup o}.
