Investigation of Topography and Electrical Properties of K<sub>0.3</sub>MoO<sub>3</sub> Thin Films
Abstract In this article we investigate topography and electrical properties of potassium blue bronze thin films by the means of atomic force microscopy. Thin films were prepared by pulsed laser depositions on two types of substrates (Al 2 O 3 and SrTiO 3 ) at different substrate temperatures and partial oxygen pressures. On the basis of topography measurements, granular nature of the films was revealed. Surface roughness, as well as the size and the orientation of grains was determined. Films deposited on SrTiO 3 substrates are quite homogeneous and the grains display ordering in preferential directions. Films on Al 2 O 3 contain randomly oriented grains. Roughness of the films increases with the increase of the deposition temperature. Electrical measurements provided qualitative information regarding the electrical properties of the films.
