Popis: Topographical and local electrical contact resistance images on surfaces of YBaCuO thin films sputtered onto MgO and SrTiO3 substrates have been obtained by AFM using a conducting tip. Typical growth exhibiting terraces of one unit cell height has been observed. Moreover, electrical images have clearly revealed electrically connected areas between grains, which can be correlated to electrical transport properties of the films.
