Sažetak
The interest in novel, often carbonaceous materials with large effective surfaces, as well as high conductivity and stability, is growing due to the downsizing of electrical devices and the demand for low-cost new materials. In particular, we present a work on a graphene- metal or metal oxide multimaterials. This type of nanomaterials shows great potential applications for electrochemical devices, transistors, batteries and biosensors. In this work the techniques used for the production of these multicomponent materials are presented: synthesis of 2D vertically aligned graphene by plasma on uniquely low temperatures, and deposition of metal and metal oxide nanoparticles and thin layers from different pulsed laser deposition procedures. The chemical and microstructural features are revealed by employing Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Near edge X-ray absorption fine structure (NEXAFS) spectroscopy. Measurements were done at the HE-SGM beamline at the synchrotron radiation facility BESSY II in Berlin (Germany). NEXAFS is a unique method to obtain information on the surface region of the sample (bonding states, fingerprint of materials). XPS in this specific case can be used with variable excitation energies to enhance surface sensitivity and excitation cross-sections.
