15 صفحه اولSuperconducting properties of iron chalcogenide thin films.
Iron chalcogenides, binary FeSe, FeTe and ternary FeTe x Se1-x , FeTe x S1-x and FeTe:O x , are the simplest compounds amongst the recently discovered iron-based superconductors. Thin films of iron chalcogenides present many attractive features that are covered in this review, such as: (i) easy fabrication and epitaxial growth on common single-crystal substrates; (ii) strong enhancement of supe...
متن کاملMicrowave Measurements on YBaCuO Thin Films and Realisation of Microwave Superconducting Devices
Two characterisations methods in microwaves are presented. They permit to obtain IS*, Rs and h for a HTS film without the need of any theoretical model for the superconductivity. The best film tested exhibits at 35GHz and 78K a Rs value of LO&. at least three times lower than the copper one. A quasi-integrated oscillator has been realised on a lcm2 area: it oscillates at 12GHz and close to liqu...
متن کاملSuperconducting properties and Hall Effect of epitaxial NbN thin films
We have measured the magnetotransport properties and Hall effect of a series of epitaxial NbN films grown on (100) oriented single crystalline MgO substrate under different conditions using reactive magnetron sputtering. Hall effect measurements reveal that the carrier density in NbN thin films is sensitive to the growth condition. The carrier density increases by a factor of 3 between the film...
متن کاملStructural, Electrical and Optical Properties of Molybdenum Oxide Thin Films Prepared by Post-annealing of Mo Thin Films
Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...
