science24 - Growth of GaN layers on silicon and …

Abstract Heteroepitaxial GaN layers have been grown on many foreign substrates such as sapphire, silicon carbide or silicon. Therein, a common feature is that the GaN epitaxy proceeds via several stages, i.e., nitridation, growth of the low temperature buffer layer, annealing, and, finally, growth of the layer with the reduced density of disloions.

Strong Plasmon Reflection at Nanometer-Size Gaps in …

We employ tip-enhanced infrared near-field microscopy to study the plasmonic properties of epitaxial quasi-free-standing monolayer graphene on silicon carbide. The near-field images reveal propagating graphene plasmons, as well as a strong plasmon reflection at gaps in the graphene layer, which appear at the steps between the SiC terraces. When the step height is around 1.5 nm, which is two

Graphene - a primer

In particular, ''silicene'' (or ''germanene''), the silicon or germanium equivalent of graphene, if they exist, may offer better compatibility with silicon processing. Led by the National Center for Scientific Research ''Demokritos'', in Greece, the project team aims to find ways to induce and stabilise the silicon and germanium and prove for the first time that silicene has a physical existence.
