چکیده

We investigate theoretically the resonant splitting of ballistic conductance peaks in magnetic superlattices. It is found that, for magnetic superlattices with periodically arranged n identical magnetic-barriers, there exists a general (n − 1)-fold resonant peak splitting rule for ballistic conductance, which is the analogy of the (n − 1)-fold resonant splitting for transmission in n-barrier electric superlattices (R. Tsu and L. Esaki, Appl. Phys. Lett. 22, 562 (1973)). PACS numbers: 73.40.Gk, 73.40.Kp, 03.65.Ge

Observation of bias-induced resonant tunneling peak splitting in a quantum dot

We have observed that, in zero magnetic field, a dc bias across a lateral confmed quantum dot (QD) splits each resonant peak in the differential conductance versus the gate voltage measurement into two. The splitting is nearly linear with the applied bias V, . Temperature-dependence study indicates that the corresponding energy separation between the two splitting peaks is close to eV, . A mode...

Quantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls

The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...

Split-Channel Ballistic Transport in an InSb Nanowire.

We report an experimental study of one-dimensional (1D) electronic transport in an InSb semiconducting nanowire. A total of three bottom gates are used to locally deplete the nanowire, creating a ballistic quantum point contact with only a few conducting channels. In a magnetic field, the Zeeman splitting of the corresponding 1D sub-bands is revealed by the emergence of conductance plateaus at ...

Quantum beating in ring conductance: Observation of spin chiral states and Berry’s phase

– We propose and demonstrate experimentally a novel configuration for observing spin interference effects in mesoscopic rings. Using this configuration, in which the conducting ring and the tangential current lead form a single collimating contact, we have observed the spin quantum beating in the Aharonov-Bohm conductance oscillations. We demonstrate that the beating is the result of the superp...

Spin-polarized proximity effect in superconducting junctions

We study spin dependent phonomena in superconducting junctions in both ballistic and diffusive regimes. For ballistic junctions we study both ferromagnet / sand d-wave superconductor junctions and two dimensional electron gas / s-wave superconductor junctions with Rashba spin-orbit coupling. It is shown that the exchange field alway suppresses the conductance while the Rashba spin-orbit couplin...
