Study of infinite layer CaCuO2/SrTiO3 interfaces
ORAL
Abstract
Thirty years after its discovery, superconductivity in cuprates still remains a lively field of research since the microscopic mechanisms leading to high Tc are not yet fully identified and understood. Recent work on the infinite layer CaCuO2 [1,2] has shown that superconductivity can occur at the interface with SrTiO3. The conduction at the interface has been related to a chemical doping mechanism with O atoms inserting into the apical position above Cu.
We present results on the study of CaCuO2/SrTiO3 bilayer structure. We investigate the influence of different growth parameters on the film quality and electrical properties explored through transport measurements.
