Structural, Mechanical, and Optical Properties of Laminate-Type Thin Film SWCNT/SiON Composites.

The development of new encapsulating coatings for flexible solar cells (SCs) can help address the complex problem of the short lifespan of these devices, as well as optimize the technological process of their production. In this study, new laminate-type protective composite coatings were prepared using a silicon oxynitride thin-film matrix obtained by curing the pre-ceramic polymer perhydropolysilazane (PHPS) through two low-temperature methods: (i) thermal annealing at 180 °C and (ii) exposure to UV radiation at wavelengths of 185 and 254 nm. Single-walled carbon nanotubes (SWCNTs) were used as fillers via dry transfer, facilitating their horizontal orientation within the matrix.

Extending the Depth of Focus of an Infrared Microscope Using a Binary Axicon Fabricated on Barium Fluoride.

Axial resolution is one of the most important characteristics of a microscope. In all microscopes, a high axial resolution is desired in order to discriminate information efficiently along the longitudinal direction. However, when studying thick samples that do not contain laterally overlapping information, a low axial resolution is desirable, as information from multiple planes can be recorded simultaneously from a single camera shot instead of plane-by-plane mechanical refocusing.

Mechanical and Optical Properties of CrO Thin Films Grown by Atomic Layer Deposition Method Using Cr(thd) and Ozone.

CrO thin films were grown on a Si (1 0 0) substrate using Cr(thd) and O by atomic layer deposition (ALD) at substrate temperatures () from 200 to 300 °C. X-ray amorphous films were deposited at a ≤ 225 °C, whereas at higher temperatures ( ≥ 250 °C), the eskolaite phase was observed in the films. The growth rate of the films increased from 0.

Nanostructures Stacked on Hafnium Oxide Films Interfacing Graphene and Silicon Oxide Layers as Resistive Switching Media.

SiO films were grown to thicknesses below 15 nm by ozone-assisted atomic layer deposition. The graphene was a chemical vapor deposited on copper foil and transferred wet-chemically to the SiO films. On the top of the graphene layer, either continuous HfO or SiO films were grown by plasma-assisted atomic layer deposition or by electron beam evaporation, respectively.

Memory Effects in Nanolaminates of Hafnium and Iron Oxide Films Structured by Atomic Layer Deposition.

HfO and FeO thin films and laminated stacks were grown by atomic layer deposition at 350 °C from hafnium tetrachloride, ferrocene, and ozone. Nonlinear, saturating, and hysteretic magnetization was recorded in the films. Magnetization was expectedly dominated by increasing the content of FeO.

Structure and Electrical Behavior of Hafnium-Praseodymium Oxide Thin Films Grown by Atomic Layer Deposition.

Crystal structure and electrical properties of hafnium-praseodymium oxide thin films grown by atomic layer deposition on ruthenium substrate electrodes were characterized and compared with those of undoped HfO films. The HfO reference films crystallized in the stable monoclinic phase of HfO. Mixing HfO and PrO resulted in the growth of nanocrystalline metastable tetragonal HfO.

Atomic layer deposition and properties of ZrO/FeO thin films.

Thin solid films consisting of ZrO and FeO were grown by atomic layer deposition (ALD) at 400 °C. Metastable phases of ZrO were stabilized by FeO doping. The number of alternating ZrO and FeO deposition cycles were varied in order to achieve films with different cation ratios.

[Revealing source and contents of dust deposits in air quality evaluation].

Identification covered a source of dust deposits in snow on stationary monitoring sites near the largest in Europe copper-nickel enterprise <>. Retrospective analysis demonstrated that considerable decrease in aerotechnogenic load resulted in disappeared technogenic phase of the dust releases, but revealed influence of neighbouring heating power station using fuel oil.

Electrochemical modification of gold electrodes with azobenzene derivatives by diazonium reduction.

An electrochemical study of Au electrodes electrografted with azobenzene (AB), Fast Garnet GBC (GBC) and Fast Black K (FBK) diazonium compounds is presented. Electrochemical quartz crystal microbalance, ellipsometry and atomic force microscopy investigations reveal the formation of multilayer films. The elemental composition of the aryl layers is examined by X-ray photoelectron spectroscopy.
