Studying single semiconductor nanowires using a hard X-ray nanoprobe — •Gema Martinez-Criado — European Synchrotron Radiation Facility, Grenoble, France

Semiconductor nanowires present great advantages for optoelectronic and spintronic nanodevices. Their applications are basically controlled by multiple property-function relationships taking place at the nanoscale in the spatial and time regimes. Only a combination of high-resolution methods offer a comprehensive characterization of their complex nature. Here we present how a multimodal hard X-ray nanoprobe addresses fundamental questions in nanowire research. Selected topics ranging from cluster formation, dopant segregation, and phase separations to quantum confinement effects are examined with sub-100 nm spatial resolution and sub-50 ps temporal resolution. This scheme opens new opportunities for structural, composition and optical investigations with large potential in materials science.
