Geometry dependence of the conductance fluctuations in metallic nanostructures

چکیده

We investigate fluctuations in the magnetoconductance of noble-metal nanostructures in a mesoscopic two-lead configuration. The samples are gold and silver wires with lengths 500 and 1000 nm and widths w between 45 and 340 nm. The correlation field Bc varies as w -~. Furthermore, the angle 0 between the direction of the magnetic field and the current is changed continuously from 90°(usual geometry) to 0 °. The dependence of Be on 0 is weaker than Bc ~x Bc±/sin 0.

Plasmonic Thermal Conductance of Stack of Metallic Nanorings

In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...

Conductance Fluctuations in a Metallic Wire Interrupted by a Tunnel Junction

The conductance fluctuations of a metallic wire which is interrupted by a small tunnel junction has been explored experimentally. In this system, the bias voltage V , which drops almost completely inside the tunnel barrier, is used to probe the energy dependence of conductance fluctuations due to disorder in the wire. We find that the variance of the fluctuations is directly proportional to V ....

Quantum transport in ferromagnetic permalloy nanostructures

We studied phase-coherent phenomena in mesoscopic permalloy Ni81Fe19 samples by exploring lowtemperature transport. Both differential conductance as a function of bias voltage and magnetoconductance of individual wires display conductance fluctuations. Analysis of these fluctuations yields a phase coherence length of 250 nm at 25 mK as well as a 1 / T temperature dependence. To suppress conduct...

Conductance fluctuations at the quantum Hall plateau transition

We analyze the conductance fluctuations observed in the quantum Hall regime for a bulk two-dimensional electron system in a Corbino geometry. We find that characteristics like the power spectral density and the temperature dependence agree well with simple expectations for universal conductance fluctuations in metals, while the observed amplitude is reduced. In addition, the dephasing length LF...

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...
