Scaling networks of compound semiconductor nanowires — •Anna Fontcuberta i Morral — Ecole Polytechnique Fédérale de Lausanne, EPFL

Nanowires are filamentary crystals with a tailored diameter between few and 100 nm [1,2]. Their shape anisotropy and size confer them with advantageous properties in a variety of areas ranging from photonics to quantum computing [3-6]. In all applications, deterministic site selective growth of nanowires is absolutely necessary. In this talk we will explain how nanowires can be obtained in arrays both free standing and lying on a substrate, in a scalable manner. We will also show how the properties such as enhanced light absorption and mobility can be engineered, opening the path to advanced functionality.
