Transport and tunneling measurements of nanostructured superconducting thin films are presented. To understand the effects of film morphology on their superconducting properties, thermal annealing experiments have been performed. The transition temperature increases with thermal annealing temperature towards the bulk value. Also, thermal annealing results in a shift of transverse phonon mode. These can be understood with changes in film morphology and suggest its importance on the superconducting state properties.
