A novel CMOS device architecture called silicon on nothing (SON) is proposed, which allows extremely thin (in the order of a few nanometers) buried dielectrics and films to be fabricated with high resolution uniformity guaranteed by epitaxial process. The SON process' dielectric (which may an oxide but also an-air gap) locally in dedicated parts chip, present advantages terms cost facility system-on-chip integration. stack itself physically confined under-gate-plus-spacer area device, thus...
The structure‐driven properties of vanadium oxide have inspired enormous developments in the last decades, especially as a smart material for energy, sensors, and optoelectronics. large variety stable metastable structures is discussed, based on calculated formation energies broad overview their structure‐related properties. established chemical deposition processes from gas phase are reviewed with particular emphasis implemented precursors obtained phases.

Sequential vapor infiltration synthesis (SVIS) within block-copolymer templates has emerged as an attractive means for the controlled formation of metal oxide nanoarrays on arbitrary substrates. This approach takes advantage molecular-level controls that are inherent in production template and exposure tools available vapor-phase growth materials.

Off-stoichiometric copper chromium oxide delafossite received lately a great interest due to its high p-type electrical conductivity and adequate optical transmittance in the visible range. However, for suitable integration active devices such as p-n junctions, transistors or optoelectronic devices, electronic properties must be efficiently tailored. Here, post-deposition thermal treatment is proven an approach finely controlling of this former degenerate semiconducting material. The...
Metal thin films are indispensable for the processing of a number modern devices that benefit from their electronic, magneto-electric and optical properties. Application trends progressively involve integration into functional which feature three-dimensional nanostructures with increasingly high aspect ratios. These conditions promote increased interest towards non-line-of-sight deposition processes such as Chemical Vapour Deposition (CVD) Atomic Layer (ALD). The metals using CVD or ALD is,...
The improvement of mechanical properties polymer-based nanocomposites is usually obtained through a strong polymer–silica interaction.
