The current-phase (I-φ) relation of a double-barrier Josephson junction with a two-gap superconductor as intermediate electrode is derived by means of a simplified version of Ohta’s model. As in conventional double-barrier Josephson junctions, a marked skewness in the I-φ curves is present. Moreover, as in heterotic Josephson devices, a reduction of the maximum Josephson current is predicted. A...
The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate the I (VJ) tunneling characteristics of the Josephson junction in our STM at a base temperature of 15 mK by means of current-biased and volt...
The heterojunction between different materials often exhibits a rectifying effect; e.g., pn junction is used for diode. On the other hand, Josephson two superconductors assumed to show symmetric response directions of current, i.e., voltage drop $V$ antisymmetric with respect sign change current $I$. However, there should be an asymmetry states charge accumulation on right and left sides juncti...
