Thin Film Superconducting Devices

Polyacetylene thin film photovoltaic devices

2014 Photovoltaic devices have been obtained by a direct polymerization of undoped (or p-type doped) thin film (CH)x layer onto a polycrystalline cadmium sulfide film. The morphology of the contact is observed by S.E.M. microscopy. The electrical characteristics of this device are studied in the dark or under illumination. The main result, at AM1, 100 mW/cm2 with doped (CH)x correspond to 0.5 p...

Electrical Characterization of Thin-film Electroluminescent Devices

Electrical characterization methods for the analysis of alternating current thinfilm electroluminescent (ACTFEL) devices are reviewed. Particular emphasis is devoted to electrical characterization techniques because ACTFEL devices are electro-optic display devices whose performance is to a large extent determined by their electrical properties. A systematic procedure for ACTFEL electrical asses...

PZT Thin-Film Meso- and Micro Devices

This paper consists of three major topics. The first topic is a review of challenges encountered in PZT thin film fabrication. Currently, sol-gel processing is one of the most promising techniques to fabricate PZT thin films. There are, however, several major challenges, including crack formation, thermally unstable electrodes, and poor piezoelectric properties. The second topic reveals some in...

Properties of mesoscopic superconducting thin-film rings: London approach

Superconducting thin-film rings smaller than the film penetration depth ~the Pearl length! are considered. The current distribution, magnetic moment, and thermodynamic potential F(H ,N ,v) for a flat, washer-shaped annular ring in a uniform applied field H perpendicular to the film are solved analytically within the London approach for a state with winding number N and a vortex at radius v betw...
