摘要：

Low-temperature (500-degrees-C) growth of YBa2Cu3Ox films by metaloganic chemical vapor deposition on (100)MgO substrates using N2O as an oxidizing agent has been investigated. Films 12 unit cells thick show superconducting onset critical temperature of 89 K and zero-resistivity critical temperature of 80 K. Films 4 unit cells thick show T(c)(zero) of 30 K. Films as thin as 3 unit ells thick reveal superconducting onset characteristics. If the topmost (cap) layer and the bottom (buffer) layer are nonsuperconducting, this result suggests that superconductivity arises even from monomolecular layer of YBa2Cu3Ox.
