Bi-based superconducting multilayers obtained by molecular beam epitaxy
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 m
