Shot noise variation within ensembles of gold atomic break junctions at room temperature.

Atomic-scale junctions are a powerful tool to study quantum transport, and are frequently examined through the mechanically controllable break junction technique. The junction-to-junction variation of atomic configurations often leads to a statistical approach, with ensemble-averaged properties providing access to the relevant physics. However, the full ensemble contains considerable additional...

Enhanced noise at high bias in atomic-scale Au break junctions

Heating in nanoscale systems driven out of equilibrium is of fundamental importance, has ramifications for technological applications, and is a challenge to characterize experimentally. Prior experiments using nanoscale junctions have largely focused on heating of ionic degrees of freedom, while heating of the electrons has been mostly neglected. We report measurements in atomic-scale Au break ...

Shot-noise suppression at two-dimensional hopping

We have used Monte Carlo simulation to calculate the shot-noise intensity SI(v) at ~two-dimensional! hopping using two models: a slanted lattice of localized sites with equal energies and a set of localized sites with random positions and energies. For wide samples we have found a similar dependence of the Fano factor F[SI(0)/2eI on the sample length L: F}L 2a where a50.8560.02 and a50.8560.07 ...

Shot noise suppression at one-dimensional hopping

We have carried out a preliminary analysis of shot noise at hopping, focusing on uniform one-dimensional ~1D! arrays of sites separated by N tunnel barriers. The results show that at low temperatures the low-frequency density of the shot noise varies from 1/N to 1 of the Schottky value, depending on the geometry, electron density, and Coulomb interaction strength. An interesting feature is v de...

Heterogeneous electron transfer at Au/SAM junctions in a room-temperature ionic liquid under pressure.

Proven electrochemical approaches were applied to study heterogeneous electron transfer (ET) between selected redox couples and gold electrodes modified with alkanethiol self-assembled monolayers (SAMs), using the room-temperature ionic liquid (RTIL) [bmim][NTf2] as reaction medium; ferrocene as freely diffusing redox probe in the RTIL was tested for ET through both thin (butanethiol) and thick...
