Zero-bias anomaly in one-dimensional tunneling contacts
نویسنده
چکیده
We study the Coulomb interaction effects on the tunneling conductance of a contact constructed of two parallel quantum wires. The following contacts are considered: two clean identical quantum wires, two disordered identical quantum wires, and asymmetric contact of one clean and another disordered quantum wires. We show that the low-voltage anomaly of the tunneling conductance is less singular than the low-energy anomaly of the one-particle density of states.

Zero-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 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...
متن کاملTunneling into multiwalled carbon nanotubes: coulomb blockade and the Fano resonance.
Tunneling spectroscopy measurements of single tunnel junctions formed between multiwalled carbon nanotubes (MWNTs) and a normal metal are reported. Intrinsic Coulomb interactions in the MWNTs give rise to a strong zero-bias suppression of a tunneling density of states that can be fitted numerically to the environmental quantum-fluctuation theory. An asymmetric conductance anomaly near zero bias...
متن کاملLow voltage I – V characteristics in magnetic tunneling junctions
In 1975, Julliere proposed a simple model for tunneling between two ferromagnetic metals, assuming that the spin is conserved in the tunneling process and that the tunneling current is proportional to the density of states of each spin at the ferromagnetic electrodes. A magnetoresistance ~MR! effect then appears when one compares the resistance for cases in which the magnetization of the electr...
متن کاملKondo conductance across the smallest spin 1/2 radical molecule.
Molecular contacts are generally poorly conducting because their energy levels tend to lie far from the Fermi energy of the metal contact, necessitating undesirably large gate and bias voltages in molecular electronics applications. Molecular radicals are an exception because their partly filled orbitals undergo Kondo screening, opening the way to electron passage even at zero bias. Whereas tha...
