For the fabrication of metallic nanowires, nanoporous templates are produced by irradiating polymeric foils at the UNILAC facility. After chemical etching of the ioninduced damage tracks, the cylindrical pores of the template are filled with metals by electrodeposition. The resulting nanowires have high aspect ratios (diameter a few ten nm, length a few ten μm). Here, we investigate the texture...

Nanowires have attracted considerable interest as the nanoscale interconnects and as the moving elements of both electronic and electromechanical devices. The evaluation of nanomechanical property plays a significant role in the development of new nanowire-based devices. Recently, we are engaged in developing an easy method for nanomechanical measurement by using an in-plane-mode piezoresistive...

We report simulations of electrically pumped waveguide emitters in which the emissive layer contains silicon nanoclusters and erbium ions. Plasmonic coupling to metallic or semi-metallic overlayers provides enhancement of the radiative rate of erbium ions, enabling high quantum efficiency emission. Using 2D and 3D finite difference time domain (FDTD) simulations we show that up to 75% of the li...

Memristors have recently generated significant interest due to their potential use in nanoscale logic and memory devices. Of the four passive circuit elements, the memristor (a two-terminal hysteretic switch) has so far proved hard to fabricate out of a single material. Here we employ electromigration to create a reversible passive electrical switch, a memristive device, from a single-component...

Nanostructured metals have received a significant amount of attention in recent years due to their exciting plasmonic and photonic properties enabling strong field localization, light concentration, and strong absorption and scattering at their resonance frequencies. Resonant plasmonic and metamaterial absorbers are of particular interest for applications in a wide variety of technologies inclu...

Mechanical properties of metallic-nanowire self-oscillations are investigated through a coherent-state analysis. We focus on elucidating the time behavior quantum energy in such oscillations, addition to analysis fluctuations, evolution eigenstates, and oscillatory trajectories. The varies somewhat randomly at first, but, later time, it undergoes stable periodical oscillation; mean stabilized m...

The simultaneous realization of nanoscale field localization and low transmission loss remains one of the major challenges in nanophotonics. Metal nanowire waveguides can fulfill this goal to a certain extent by confining light within subwavelength space, yet their optical performances are still restricted by the tradeoff between confinement and loss, which results in quite limited propagation ...

We propose a plasmo-thermomechanical mid-infrared detector operating at 4.3 μm wavelength. The design utilizes an array of the bimetallic fishbone nanowires that are suspended 50 nm above a 1.5 μm × 0.3 μm silicon nitride waveguide to create a leaky wave radiation. Moreover, the thermo-mechanically actuated nanowire will induce evanescent wave modulation that can be detected by the leaky wave o...
