Carbon ceramics from plants: Graphitization of biomorphic matrixes
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2016, Vol 19, Issue 1
Abstract
Properties of matrixes obtained from plants at various pyrolysis temperatures have been discussed. The article is devoted to graphitization of carbon matrixes obtained from plants. All stages of production, starting from preparation of the precursors up to high-temperature pyrolysis, have been considered together with some specific properties of matrixes at each stage. Previously unexplored new structural surface changes have been found. The use of potassium-doped wooden precursors showed the graphitization property of the matrix surfaces and allowed to form the matrix capillary wall coating with layers of crystalline graphite as well as graphene flakes and films with a low number of defects. New possibilities to apply these matrixes as examples of ultracapacitor, power unit filter electromagnetic interference and audio power amplifier antiresonance element have been discussed as well.

Enhanced optical transmission of the triple-layer resonant waveguide structure
In this paper, we propose and demonstrate a novel guided-mode resonant filter based on a metallic grating sandwiched between two dielectric layers for TE polarization. A theoretical model based on rigorous coupled wave a...
Peculiarities of photoluminescence spectra behavior in SiC crystals and films during phase transformations
Peculiarities of photoluminescence spectra behavior in SiC crystals and thin films with in-grown defects during phase transformations have been studied. On the deep-level(DL)-spectra, as an example, their characteristics...
Structural, electrical and optical investigations of Cu6PS5Br-based thin film deposited by HiTUS technique
Cu6.35P1.77S4.72Br0.15 thin film was obtained using the high target utilization sputtering onto c-cut sapphire substrates. X-ray diffraction studies show the film to be amorphous with some crystalline inclusions. SEM inv...
Features of mechanical scanning probe lithography on graphene oxide and As(Ge)Se chalcogenide resist
ombined mechanical scanning probe lithography (SPL) approach applied for the direct mask-less modification of graphene oxide (GO) flakes and the mask patterns engraving in layers of chalcogenide resist with a nanometer s...
Nanostructuring the SiOx layers by using laser-induced self-organization
The processes of laser-induced transformation of SiOx oxide layers into the nanocomposite ones were studied. The possibility of phase separation in the form of Si nanocrystals surrounded by corresponding SiO2 oxide matri...
