Our research activities are centered on the research of novel semiconductor nanostructure combinations, using mainly nanowires, which are filamentary crystals with a very high ratio of length to diameter, the latter being in the nanometer range.
Semiconductor nanowires are of significant interest from a fundamental point of view as they exhibit new physical and chemical properties owing to their large surface-to-volume ratio, low dimensionality and confinement in one dimension. From a technological perspective, they constitute attractive building blocks for the assembly of novel nano-electronic and nano-photonic systems, as well as biochemical sensor.
Our synthesis methods span from the standard Chemical Vapor Deposition to catalyst-free Molecular Beam Epitaxy.
Examples of our experimental methods are to study the fundamental properties that span from optical and Raman spectroscopy to magnetotransport.
