Nanowires are filamentary crystals with a tailored diameter that can be obtained using a
plethora of different synthesis techniques. In this review, we focus on the vapor phase …

Photoelectrochemical (PEC) water splitting is a promising approach for hydrogen production
using solar energy with zero emissions. However, the solar-to-hydrogen efficiency (STH) of …

Solar water splitting is one of the key steps in artificial photosynthesis for future carbon-
neutral, storable and sustainable source of energy. Here we show that one of the major …

We report the spectral imaging in the UV to visible range with nanometer scale resolution of
closely packed GaN/AlN quantum disks in individual nanowires using an improved custom …

A cornerstone in the successful application of semiconductor nanowire devices is controlled
impurity do**. In this review article, we discuss the key results in the field of semiconductor …

GaN nanowires have been grown by molecular beam epitaxy either catalyst-free or catalyst-
induced by means of Ni seeds. Under identical growth conditions of temperature and V/III …

Using molecular beam epitaxy, self-assembled AlGaN nanowires are grown directly on Ta
and Ti foils. Scanning electron microscopy shows that the nanowires are locally textured …

GaN nanowires (NWs) doped with Mg as a p-type impurity were grown on Si (111)
substrates by plasma-assisted molecular beam epitaxy. In a systematic series of …

We demonstrate an all-epitaxial and scalable growth approach to fabricate single-crystalline
GaN nanowires on graphene by plasma-assisted molecular beam epitaxy. As substrate, we …

Semiconductor nanowires (NWs) have been investigated for decades, but their application
into commercial products is still difficult to achieve, with triggering causes related to the …
