Pulsed laser deposition of Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub 7-{delta}} films grown at heater temperature of 720 and 800 C on SrTiO{sub 3} and MgO substrates with thickness ranging from a nominal 5 unit cells to 200 nm were studied by STM and SEM. Size and density of particles present in the films were found to depend on film thickness, growth temperature and substrate. STM images indicate a correlation between film growth mode and particle density: the onset of big particles comes after the growth mode changes from layer-like to island growth.
