GRANULAR YBaCuO FILMS PREPARED BY METALORGANIC CHEMICAL AEROSOL DEPOSITION TECHNOLOGY
نویسندگان
چکیده
Fine-grain thin superconducting films can be prepared by metalorganic Chemical Aerosol Deposition Technology (CADT). In this paper, we present the preparation and properties of YBa2Cu307_ x films on the different substrates, Si and SrTiO 3 (100). It is shown that the zero-resistance temperature (Tc,0) of the films on SrTiO 3 substrates is about 90 K, and the critical current density (Jc) at 77 K is above 104 A/cm 2. In addition, these films exhibit significant grain-boundary weak link behaviour, which is very promising for applications in electronic devices.

Optical Response of Highly Granular Ybacuo Films Prepared by Non-vacddm Aerosol Deposition
Highly granular YBaCuO films on SrTlO, substrates wlth T,,,-90K and J,>lO' A/cm2 were prepared by non-vacuum aerosol deposition. The optical response for these films was investigated on a 10 x 10 pm2 mlcrobrldge. Besides a bolometrlc response around the transition temperature, a sharp response peak was observed at low temperature and high bias current using a He-Ne laser (0.63pm wavelength) lll...

INTRODUCTION Thin films of different materials like metals, oxides, sulphides, etc., can be deposited by the Chemical Aerosol Deposition Technology (CADT). A liquid aerosol is used to transport the chemical reactants to the vicinity of a heated subslrate. Conditions are set to obtain an heterogeneous reaction (CVD mode) between the evaporated reactants and the substrate (Maatman et al. 1988). T...

TiO2 nanostructured films were synthesized by an aerosol chemical vapor deposition (ACVD) method with different controlled morphologies: columnar, granular, and branched structures for the photocatalytic inactivation of Escherichia coli (E. coli) in water. Effects of film morphology and external applied voltage on inactivation rate were investigated. As-prepared films were characterized using s...
متن کاملCopper and Copper Oxide Thin Films Obtained by Metalorganic Microwave Plasma Cvd
Microwave Plasma Enhanced Chemical Vapor Deposition (MPECVD) is an innovative technique allowing the direct preparation, at low temperature, of different valence states of copper (Cu°, Cu, Cu). The precursor used is a volatile metalorganic one (copper acetylacetonate) with helium as a carrier gas. The precursor is then transported in a remote plasma of Ar, A1/O2 or A r / ^ O gas at low pressure...
