Superconducting La2-xBaxCuO4+delta d ( LBCO) films have been deposited on 10 x 10 mm(2) ( 100) LaAlO3 substrates using an in- situ MOCVD process and adopting the multi- component single source approach. Highly c- axis oriented films are fabricated and X- ray diffraction ( XRD) ( 103) pole figures point to the epitaxial nature of the LBCO films. Scanning electron and atomic force microscopy images show highly homogeneous surfaces. Energy dispersive ( EDX) and wavelength dispersive X- ray ( WDX) analyses show a good homogeneity over all the 10 x 10 mm(2) substrate and the absence of any F or C contaminations.

Abstract
Superconducting La2-xBaxCuO4+delta d ( LBCO) films have been deposited on 10 x 10 mm(2) ( 100) LaAlO3 substrates using an in- situ MOCVD process and adopting the multi- component single source approach. Highly c- axis oriented films are fabricated and X- ray diffraction ( XRD) ( 103) pole figures point to the epitaxial nature of the LBCO films. Scanning electron and atomic force microscopy images show highly homogeneous surfaces. Energy dispersive ( EDX) and wavelength dispersive X- ray ( WDX) analyses show a good homogeneity over all the 10 x 10 mm(2) substrate and the absence of any F or C contaminations.File in questo prodotto:
