Thickness dependence on superconducting and structural properties of thin fese0,5te0,5 films

In the present work the influence of the layer thickness of FeSe0,5Te0,5 on the crystalline and superconducting properties of films deposited on iron (Fe) buffered MgAl2O4 substrates by pulsed laser deposition (PLD) is investigated. The superconducting layer thicknesses of the films prepared are ~55...

El espesor de las capas superconductoras producidas son ~55nm y ~134nm. La película con menor espesor presenta mejores propiedades de textura (crecimiento orientado) y una menor rugosidad superficial (RMS); verificadas por difracción de rayos X y AFM respectivamente. Esta misma película presenta una transición marcada al estado superconductor y una mayor temperatura crítica a diferencia de la película de mayor espesor.
