“…On another note, Si NPs have been successfully hyperdoped with a wide range of different elements including transitions metals, − Li, Au, and Er, − as well as group III − and group V ,,− ,,− elements. However, reports on impurity concentrations exceeding the thermodynamic limit in Si nanocrystals are very rare.…”

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 advanced device architectures, research on allotropes and metastable compositions has gained considerable interest. Several new approaches now allow the controlled formation of specific allotropes in the nanostructured form as well as chemical compositions not attainable by traditional synthesis protocols. The conditions applied to form these metastable solid solutions and allotropes are usually far from thermodynamic equilibrium or rely on unconventional templates. The increased interest in the field of metastable group IV nanostructures arises from their altered physical properties, including tunable, direct bandgaps with energies equivalent to the near- to mid-infrared spectral region as described for materials such as Ge1–x Sn x and hexagonal Si1–x Ge x . The implementation of these material characteristics in complementary metal oxide semiconductor (CMOS) processes are desirable for applications in electronics, optoelectronics, sensors, optics, etc. but also their use as nonsurface bound nanoparticles in sensing, nanobiotechnology and nanomedicine can offer additional opportunities. This review article highlights both the important advancements and still open questions for the continued development of these nanoscaled materials for next-generation device concepts.

“…They possess good anti-wear behaviour and high corrosion resistance due to their inert nature. [20][21][22] They have high hardness, and in tribological contacts, they undergo a graphitization process leading to very low friction and reduced wear in boundary lubricating conditions. 23,24 Moreover, DLC coatings can act as a physical barrier hindering corrosion and tribocorrosion on the metal surfaces.…”
