Nanostructured lanthanum cobaltite thin films have been grown on silica substrates by hybridchemical vapor deposition/sol-gel approaches. The refractive index and the extinction coefficient ofthe specimens have been determined in the spectral range of 0.75-6.5 eV by spectroscopicellipsometry. The conductivity of the films as a function of temperature has been also investigated,highlighting the different electrical behavior of LaCoO3 nanosystems as a function of the adoptedsynthetic strategy.

Abstract
Nanostructured lanthanum cobaltite thin films have been grown on silica substrates by hybridchemical vapor deposition/sol-gel approaches. The refractive index and the extinction coefficient ofthe specimens have been determined in the spectral range of 0.75-6.5 eV by spectroscopicellipsometry. The conductivity of the films as a function of temperature has been also investigated,highlighting the different electrical behavior of LaCoO3 nanosystems as a function of the adoptedsynthetic strategy.File in questo prodotto:
