III/V semiconductor nanostructures have significant potential in device applications, but effective surface passivation is critical due to their large surface-to-volume ratio. For InP such passivation has proven particularly difficult, with substanti

Thanks to their uniqueness, nanowires allow the realization of novel semiconductor crystal structures with yet unexplored properties, which can be key to overcome current technological limits. Here we develop the growth of wurtzite GaP/In(x)G(x)G(1-x

A nanowire solar cell can fundamentally outperform its planar counterpart due to efficient light outcoupling. We demonstrate a 70mV higher Voc than a planar structure of identical material, as well a a new world record nanowire solar cell efficiency.

We demonstrate an efficiency enhancement of an InP nanowire (NW) axial p-n junction solar cell by cleaning the NW surface. NW arrays were grown with in situ HCl etching on an InP substrate patterned by nanoimprint lithography, and the NWs surfaces we

Approaching the theoretically limiting open circuit voltage (V-oc) of solar cells is crucial to optimize their photovoltaic performance. Here, we demonstrate experimentally that nanostructured layers can achieve a fundamentally larger Fermi level spl

Photoelectrochemical hydrogen production from solar energy and water offers a clean and sustainable fuel option for the future. Planar III/V material systems have shown the highest efficiencies, but are expensive. By moving to the nanowire regime the

Carrier capture and relaxation in self-assembled InAs/GaAs quantum dots (QDs) have been studied, using bleaching rise time measurements for both the ground state (GS) and the first excited state (ES) transition, as a function of temperature (5, 77 an
