Since the positive influences of defects on the performance of electroceramics were
discovered, investigations concerning on defects and aliovalent doping routes have grown …

The nanowire geometry provides potential advantages over planar wafer-based or thin-film
solar cells in every step of the photoconversion process. These advantages include reduced …

In our environment, the large availability of wasted heat has motivated the search for
methods to harvest heat. As a reliable way to supply energy, SiGe has been used for …

In this Colloquium the theory of silicon nanowires is reviewed. Nanowires with diameters
below 10 nm are the focus, where quantum effects become important and the properties …

Incorporation of catalyst atoms during the growth process of semiconductor nanowires
reduces the electron mean free path and degrades their electronic properties. Aberration …

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 …

Sintering process studies have re-emerged strongly in the past decade due to extensive
discussions about the stabilization of nanoparticles and nanostructures, and the …

The formation mechanisms of epitaxial GaN nanowires grown within a self-induced
approach by molecular-beam epitaxy have been investigated at the onset of the nucleation …

Diffusion is one of the fundamental processes that govern the structure, processing, and
properties of materials and it plays a crucial role in determining device lifetimes. However …

Rare-earth doped nitride attracts considerable attention because of its application as a light-
emitting phosphor. The atomic site of dopants in a crystal is important for the development of …
