We study the structure and the electronic properties of Au nanocontacts created by controlled electromigration of thin film devices, a method frequently used to contact molecules. In contrast to electromigration testing, a current is applied in a cyclic fashion and during each cycle the resistance increase of the metal upon heating is used to avoid thermal runaway. In this way, nanometer sized-gaps are obtained. The thin film devices with an optimized structure at the origin of the…

Electromigration and the structure of metallic nanocontacts
This article reviews efforts to structurally characterize metallic nanocontacts. While the electronic characterization of such junctions is relatively straight forward, usually it is technically
Controlled electromigration of thin Pb films started from the normal and from the superconducting state
We have investigated the electromigration of thin Pb films with a weak link, performing the main sample fabrication steps in ultra-high vacuum and avoiding organic chemicals. In the normal state,


Resistance-voltage dependence of nanojunctions during electromigration in ultrahigh vacuum
The electrical resistance $R$ of metallic nanocontacts subjected to controlled cyclic electromigration in ultrahigh vacuum has been investigated in situ as a function of applied voltage $V$. For
Two-dimensional simulations of temperature and current-density distribution in electromigrated structures
We report on the application of a feedback-controlled electromigration technique for the formation of nanometre-sized gaps in mesoscopic gold wires and rings. The effect of current density and
In situ atomic force microscopy imaging of structural changes in metal nanowires during feedback-controlled electromigration
The authors present the real-time atomic force microscopy (AFM) imaging of structural changes in gold (Au) nanowires during the feedback-controlled electromigration (FCE) process. The resistance
Temperature control of electromigration to form gold nanogap junctions
Controlled electromigration of gold nanowires of different cross-sectional areas to form nanogap junctions is studied using a feedback method. A linear correlation between the cross-sectional area of

Nanometer-sized gap (or nanogap) is one of the most fundamental devices in the nanotechnology field. Park et. al., first proposed the open-circuit electromigration method to fabricate nanogaps, but
In situ TEM and STEM studies of reversible electromigration in thin palladium-platinum bridges.
The reversible electromigration in Pd-Pt nanobridges is investigated by means of in situ electron microscopy to determine the material transport and is dominated by atom diffusion at grain boundaries on the free surface.
Controlled fabrication of nanogaps in ambient environment for molecular electronics
We have developed a controlled and highly reproducible method of making nanometer-spaced electrodes using electromigration in ambient lab conditions. This advance will make feasible single molecule
Scanning probe microscopy imaging of metallic nanocontacts
We show scanning probe microscopy measurements of metallic nanocontacts between controlled electromigration cycles. The nanowires used for the thinning process are fabricated by shadow evaporation.
Conductance of gold nanojunctions thinned by electromigration
We investigate nanocontact formation by thermally assisted electromigration of gold nanowires. An automatic cycling process allows us to follow a line of constant power dissipated at the nanocontact
Feedback controlled electromigration in four-terminal nanojunctions
The authors have developed a fast, yet highly reproducible method to fabricate metallic electrodes with nanometer separation using electromigration (EM). They employ four terminal instead of
