Effects of resonant interface states on tunneling magnetoresistance

Based on model and ab initio calculations we discuss the effect of resonant interface states on the conductance of epitaxial tunnel junctions. In particular we show that the ‘‘hot spots’’ found by several groups in ab initio calculations of symmetrical barriers of the ki-resolved conductance can be explained by the formation of bonding and antibonding hybrids between the interface states on bot...

Resonant Tunneling throughQuantumDots

Motivated by recent experiments we analyse a new setup of capacitively coupled semiconductor quantum dots. We identify a region where Kondo-assisted tunneling should be observable. We nd an eeective mapping to a single quantum dot with controllable multi-level structure. We study electron transport through strongly coupled quantum dots in the presence of strong Coulomb repulsion and coupling to...

On-site Coulomb repulsion and resonant tunneling.

We study the eAect of on-site Coulomb repulsion on the process of resonant tunneling. We find that the tunneling peak results from a crossover from the high-temperature Kondo phase to the lowtemperature mixed-valence phase of the system when the chemical potential is varied across the on-site localized-state energy. Consequently, the line shape is non-Lorentzian, with rather unusual temperature...
