摘要
FeSe1-xTex thin films with a PbO-type structure are successfully grown on MgO(100) and LaSrAlO4(001) substrates from FeSe0.5Te0.5 polycrystalline targets by pulsed laser deposition. The film deposited on the MgO substrate (film thickness similar to 55 nm) shows superconductivity at 10.6 K (onset) and 9.2 K (zero resistivity). On the other hand, the film deposited on the LaSrAlO4 substrate (film thickness similar to 80 nm) exhibits only the onset of superconducting transition at 3.9 K. but does not show zero resistivity above 2 K. This indicates the strong effect of epitaxial strain on the superconducting properties of FeSe1-xTex thin films. (C) 2010 Elsevier B.V. All rights reserved.
