Opis:: Visibility and simple optical diagnostics possibilities of graphene layers on dielectric and semiconductor substrates at the Brewster angle are analyzed. The analysis is based on a numerical simulation. Several oxide semiconductors (ITO, ZnO, TiO2), weakly absorbing Si, and strongly absorbing GaAs are considered. It is shown that at the Brewster angle the optical contrast of graphene flakes on a bare semiconductor substrate is actually strong enough to see them under an optical microscope and there is really no need to create an additional interference film on the substrate.

Opis:: Fluorine doped tin oxide (FTO) films were successfully prepared on glass and quartz substrate at a substrate temperature equal to for different fluorine doping (0, 0.05, 0.1, 0.15) by a homemade spray pyrolysis technique. The spray solution prepared from tin tetrachloride pentahydrate dissolved in distilled water at concentration and ammonium fluoride was added into the solution for fluorine doping. X-ray diffraction patterns of the spray-deposited (SnO2: F) films for different fluorine doping show that all the diffractograms contain the characteristic SnO2 orientations. The matching of the observed and standard d-values confirm that the deposited films are of tin oxide with tetragonal structure and the films are polycrystalline with (110) as a preferred growth orientation. The surface morphology of thin film has been examined by atomic force microscopy (AFM). The average transmittance in the visible region (at 550 nm) has been found (40 %, 47 %, 52 %, 59 %, 61 %) for the fluorine doping (0, 0.05, 0.1, 0.15, 0.2) respectively.
