SrTQ as substrate for coherently tilted epitaxial YBasCuaO , thin films
نویسندگان
چکیده
High T, superconducting YBazCusO, (YBCO) thin films have been prepared on (305) SrTiOs (STO) substrates. X-ray diffraction analysis and Rutherford backscattering experiments reveal that the c-axis of the layers is directed along the [OOl] ST0 axis. Bragg reflection measurements from YBCO lattice planes with high h, k, and I indices confirm that the film growth is epitaxial and almost single domain. For the critical current density j,(77 K) values of 2>( lo6 and 1 x lo3 A/cm2 have been found in the [OlO] and [SO]] YBCO directions, respectively.

Ultraviolet detectors based on annealed zinc oxide thin films: epitaxial growth and physical characterizations
In this report, ultraviolet (UV) detectors were fabricated based on zinc oxide thin films. The epitaxial growth of zinc oxide thin films was carried out on bare glass substrate with preferred orientation to (002) plane of wurtzite structure through radio frequency sputtering technique. The structural properties indicated a dominant peak at 2θ=34.28º which was matched with JCPDS reference card N...
متن کاملOPTICAL PROPERTIES OF THIN Cu FILMS AS A FUNCTION OF SUBSTRATE TEMPERATURE
Copper films (250 nm) deposited on glass substrates, at different substrate temperatures. Their optical properties were measured by ellipsometery (single wavelength of 589.3 nm) and spectrophotometery in the spectral range of 200–2600 nm. Kramers Kronig method was used for the analysis of the reflectivity curves of Cu films to obtain the optical constants of the films, while ellipsometery measu...

PbZr0.2Ti0.8O3~PZT! thin films with and without La0.5Sr0.5CoO3~LSCO! electrodes were grown epitaxially on ~001! SrTiO3 at 650 °C by pulsed laser deposition. The domain structure of the 400 nm thick PZT films with different electrode layer configurations was investigated by x-ray diffraction and transmission electron microscopy. The c-domain fractions of the PZT films with no electrode layer, wi...
متن کاملEffect of Elastic Anisotropy on Surface Pattern Evolution of Epitaxial Thin Films
Stress-induced surface instability and evolution of epitaxial thin films leads to formation of a variety of self-assembled surface patterns with feature sizes at microand nanoscales. The anisotropy in both the surface and bulk properties of the film and substrate has profound effects on the nonlinear dynamics of surface evolution and pattern formation. Experimentally it has been demonstrated th...
