Metallic nanowires are unique materials in the large family of plasmonic nanostructures that, nowadays, can be fabricated using various methods with high precision and control. First of all, they exhibit plasmon resonance, which is rather broad, covering the visible spectral range and even stretching out to the infrared. In this way, metallic nanowires can be used for plasmon-manipulation of the optical properties of dyes, fluorescent proteins, semiconductor quantum dots, rare-earth ions, etc. In addition, their tens-of-microns lengths facilitate efficient propagation of energy via surface plasmon polaritons over distances much larger than the optical resolution of microscopy systems. This property allows for remote optical addressing and readout, as well as photoactivation of light-dependent processes. Last, but not least, the positions of the nanowires can be determined with relatively simple optical systems, making them applicable as geometric platforms. The combination of all three characteristics of metallic nanowires has led to a multitude of fundamental and applied research, with the latter focusing primarily on optoelectronics, photovoltaics and sensorics. The goal for this Special Issue is to describe the recent developments of this rapidly developing interdisciplinary research field. Therefore, we invite you to submit manuscripts for this Special Issue. Full papers, communications, and reviews are all welcome.

Quantifying Joule heating and mass transport in metal nanowires during controlled electromigration
Dr. Mamiko Yagi and Dr. Jun-ichi Shirakashi
Nanoscale heat dissipation (Joule heating) and mass transport in electromigration (EM) have attracted considerable attention in recent years because the EM can be useful in preparing the electrodes with nanoscale gaps (nanogaps) in metal nanowires. Here, EM-driven movement of voids in different shaped Au nanowires with widths of 50-300 nm was directly observed by performing atomic force microscopy (AFM). The AFM measurements allowed us to detect the surface and depth changes during a computer controlled EM. Using these data, we estimated and captured average mass transport rate of 105-6 atoms/s. In addition, we investigated the heat dissipation in straight and bowtie-shaped nanowires. The maximum Joule heating power of straight nanowires was three times higher than that of bowtie-shaped nanowires, indicating that EM in bowtie-shaped nanowires can be triggered by lower power. Moreover, based on the power dissipated by the nanowires, the local temperature during EM was estimated. It was found that the local temperature of bowtie-shaped nanowires at the 1st onset of EM was around 400 K and increased during the process while the current density remained on the order of 108 A/cm2. It is noted that despite lower power this tendency was quite similar to that of straight nanowires. These results suggest that EM-driven mass transport was controlled at temperatures much smaller than the melting point of Au. Insights gained from this study will be able to help develop a more concrete understanding of the matter fluxes during EM.
