3. 7. Nonequilibrium Effects in Mesoscopic Josephson Junctions

   Författare :Peter Samuelsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis we present a unified scattering approach to current transport in mesoscopic Josephson junctions out of equilibrium. A nonequilibrium situation is created by either quasiparticle injection into the normal part of the junction, or by applying a dc-voltage between the two superconducting electrodes. LÄS MER

4. 8. Charging effects in small capacitance Josephson junction circuits

   Författare :Peter Ågren; KTH; []
   Nyckelord :;

   Sammanfattning : This thesis describes fabrication, measurements and analysisof two different Josephson junction circuits; the Cooper pairtransistor (CPT) and the one dimensional Josephson junctionarray (JJA). All experiments are conducted in a dilutionrefrigerator with a base temperature of 15{30 mK. LÄS MER

7. 10. Elastic and inelastic scattering effects in conductance measurements at the nanoscale : A theoretical treatise

   Författare :Peter Berggren; Jonas Fransson; Wolfgang Belzig; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; Scanning tunneling microscopy; tunnel junctions; molecular graphene; paramagnetic molecules; spin interaction; nano electromechanical system; Josephson junction; superconductivity; chaos; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Elastic and inelastic interactions are studied in tunnel junctions of a superconducting nanoelectromechanical setup and in response to resent experimental superconducting scanning tunneling microscope findings on a paramagnetic molecule. In addition, the electron density of molecular graphene is modeled by a scattering theory approach in very good agreement with experiment. LÄS MER
