Probing intrinsic properties of high-temperature superconductors — •Holger Motzkau and Thorsten Jacobs — Experimental Condensed Matter Physics, Department of Physics, Stockholm University, AlbaNova University Center, 106 91 Stockholm, Sweden
Some high-temperature superconductors naturally consist of superconducting and insulating crystal layers that form intrinsic Josephson junctions. They allow tunneling experiments that give a deep insight into material properties and mechanisms of superconductivity. We use crogen-free cryostats to investigate the interplay between superconductivity, magnetic fields, THz radiation, phonons, and other quasi particles in cuprates such as Bi2Sr2CaCu2O8+x. Samples are fabricated in a clean room environment using nanofabrication methods such as thin film deposition, dry etching, focused ion beam, and electron beam lithography. Another focus of the group is the improvement of nanocalorimetry for the investigation of thermodynamic properties of superconductors.
