Bi-based superconducting multilayers obtained by molecular beam epitaxy
(1999) In International Journal of Modern Physics B 13(9-10). p.991-996- Abstract
High temperature superconducting multilayers have been obtained depositing Bi2Sr2CuO6+δ (2201) and ACuO2 layers, where A is C a or Sr, by Molecular Beam Epitaxy (MBE) on M gO and SrTiO3 substrates. The samples, formed by a sequence of 2201/ACuO2 bilayers, have different thickness of ACuO2 layers while the thickness of the 2201 layers is kept constant. The surface structure of each layer has been monitored by in situ Reflection High Energy Electron... (More)
High temperature superconducting multilayers have been obtained depositing Bi2Sr2CuO6+δ (2201) and ACuO2 layers, where A is C a or Sr, by Molecular Beam Epitaxy (MBE) on M gO and SrTiO3 substrates. The samples, formed by a sequence of 2201/ACuO2 bilayers, have different thickness of ACuO2 layers while the thickness of the 2201 layers is kept constant. The surface structure of each layer has been monitored by in situ Reflection High Energy Electron Diffraction (RHEED) analysis which has confirmed a 2D nucleation growth. X-ray diffraction (XRD) analysis has been used to confirm that the layered structure has been obtained. Moreover, a one-dimensional X-ray kinematic diffraction model has been developed to interpret the experimental data and to estimate the period of the multilayers. Resistive measurements have shown that the electrical properties of the samples strongly depend on the thickness of the ACuO2 layers.
