In this paper we present results of structural and topographical studies of C-Ni nanocomposite films with different Ni content. Films were obtained by PVD method. Their structure was investigated by Raman and FTIR spectroscopy and topography by AFM. Typical field emission current from these films is few μA (up to 10 μA) for 3kV anode-cathode voltage and 0.1mm anode-cathode distance.
Non-hydrogenated high sp3 content diamond-like carbon (DLC) has been subjected to intensive research efforts over the last three decades owing to its superior material properties. By introducing some metals/dopants into DLC film during deposition, the microstructure and properties of the films can be further modified, where studies have demonstrated it as an effective method to reduce the internal...
Characterisation of C-Pd films composed of carbon and palladium nanograins and obtained in two-steps method is presented. Film obtained in first step exhibits multiphase structure composed of nanograins of fullerenes, amorphous carbon and palladium nanocrystals. This film is modified in CVD process. Final films has porous carbonaceous form. All films were studied by scanning electron microscopy (SEM),...
This paper describes the possibilities of obtaining nanostructured TiO2 using Spray Pyrolysis Deposition and its application in a solid state solar cell (FTO/ TiO2 In2S3/ CuSbS2/ graphite). Nanostructured TiO2 films are deposited from ethanolic solution of titanium (IV) isopropoxid, (TTIP, 99.99%, Sigma-AIdrich), and acetilacetonate, (AcAc, 99+%, Aldrich); two parameters are proposed for investigation:...
In this work and with a view to optimizing their FE properties, LaS films of increased crystallinity were obtained by PLD on lattice matched MgO substrates, at elevated substrate temperatures and in a background gas of H2S. The thin films have been characterized by high resolution transmission electron microscopy, atomic force microscopy (AFM), X-ray diffraction, ellipsometry and Raman spectroscopy...
