In this article, the work on Ge nanocrystals embedded in dielectric films formed by phase
separation from supersaturated solid solutions is reviewed. Different methods to synthesize …

Tandem PV cells–with their increased efficiency due to a multi-band gap approach–usually
involve expensive materials and fabrication. Thin film approaches, with an engineered …

Silicon exhibits a large variety of different bulk phases, allotropes, and composite structures,
such as, eg, clathrates or nanostructures, at both higher and lower densities compared with …

Oxide-embedded and oxide-free alkyl-terminated silicon (Si) nanocrystals with diameters
ranging from 3 nm to greater than 10 nm were studied by Raman spectroscopy. For ligand …

Large-volume, phase-pure synthesis of BC8 silicon (I a 3¯, c I 16) has enabled bulk
measurements of optical, electronic, and thermal properties. Unlike previous reports that …

Silicon nanocrystals (Si-nc) is an enabling material for silicon photonics, which is no longer
an emerging field of research but an available technology with the first commercial products …

In the past decades, group IV nanowires and nanoparticles have been the subject of
extensive research. Beside tremendous progress in morphological control and integration in …

We present density functional and many body perturbation theory calculations of the
electronic, optical, and impact ionization properties of Si nanoparticles (NPs) with core …

Precipitation and crystallization of Si nanocrystals have been monitored by means of Raman
spectroscopy. SiO x films with different compositions have been deposited by low-pressure …

Silicon quantum dot (Si QD) solar cells offer the potential to tune the effective band gap
through quantum confinement and hence allow fabrication of optimised tandem devices in …
