The temporal evolution of the scanning tunneling microscope image of a c-axis laser-ablated YBa2Cu3OT\_z film on a MgO substrate was studied at room temperature in air. The tunneling spectra of the junctions with Au, Pb, Pt-Ir or W tip-YBCO films were measured at liquid-helium temperature. A gap-lik
