Multifunctional semiconductor nanowires for photonic applications — •Carsten Ronning — Institut für Festkörperphysik, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, 07743 Jena

Semiconductor nanowires are of major importance within the area of nanotechnology, and are usually synthesized using the so-called vapor-liquid-solid (VLS) mechanism. They serve as both functional units and as the wires that access them; therefore, they are ideal building blocks for multifunctional nanoscale devices. Applications and proto-type devices based on semiconductor nanowires have been realized in various areas: in electronics, photonics, mechanics, and sensors. I will just summarize and focus this presentation on the use of zinc oxide nanowires for photonic applications: this will include waveguiding [1], light emitting diodes [2] and lasers [3].
