Electron-Electron Interaction in Linear Arrays of Small Tunnel Junctions
We have calculated the spatial distribution of the electrostatic potential created by an unbalanced charge q in one of the conducting electrodes of a long, uniform, linear array of small tunnel junctions. The distribution describes, in particular, the shape of a topological single-electron soliton in such an array. An analytical solution obtained for a circular cross section model is compared w...
متن کاملZero-bias anomaly in CrO2 junctions
– CrO2 thin films, with crystallites of several microns size, provide the opportunity for the investigation of the intergrain tunneling between a few crystals separated by a 1–2 nm thick Cr2O3 film. A pronounced zero-bias anomaly of the conductance is found at low temperatures. Combined photoemission and inverse photoemission temperature-dependent studies confirm the occurrence of Coulomb block...
متن کاملNonequilibrium Electron Cooling by NIS Tunnel Junctions
We discuss the theoretical framework to describe quasiparticle electric and heat currents in NIS tunnel junctions in the dirty limit. The approach is based on quasiclassical Keldysh-Usadel equations. We apply this theory to diffusive NIS′S tunnel junctions. Here N and S are respectively a normal and a superconducting reservoirs, I is an insulator layer and S′ is a nonequilibrium superconducting...
متن کاملTheory of the zero-bias anomaly in magnetic tunnel junctions: Inelastic tunneling via impurities
Using the closed-time path-integral approach, we nonperturbatively study inelastic tunneling of electrons via magnetic impurities in the barrier accompanied by phonon emission in a magnetic tunnel junction. The spectrum density of phonon emission is found to show a power-law infrared singularity ,v−s1−gd with g the dimensionless electron-phonon coupling. As a consequence, the tunneling conducta...
