To investigate the influence of temperature on nucleation and growth Ti 3 SiC 2 , Ti–Si–C thin films were deposited by magnetron sputtering from elemental targets Ti, Si C Si(100) Al O substrates at <200°C. Subsequently, as annealed in vacuum 800, 950, 1100 1200°C respectively. The consisted amorphous TiC, free C, determined X-ray diffraction photoelectron spectroscopy. Annealing <950°C resulted improved crystallinity TiC formation x 5 phases. However, phase forms 1100°C owing to...
A SiC coating for carbon–carbon composites was prepared by the pack cementation method in an argon atmosphere. The influence of silicon content powder on microstructure and antioxidation property coatings were studied. As content's <82·4 wt-%, as obtained possesses a porous structure with β-SiC phase. While is up to 85·7 dense consisting β-SiC, α-SiC Si. thickness increases increase content. Oxidation test shows that improves greatly >82·4 wt-%.
The VO 2 thin film has the advantage of thermally controlled insulator-metal phase transition. Based on this, we presented a reconfigurable metamaterial with switchable wideband absorption and sensing at THz band in this paper. At low temperature ([Formula: see text][Formula: text]S/m), can realize nearly perfect range 6.88–9[Formula: text]THz. When rises to certain extent an peak which be used appears 4.08[Formula: text]THz permittivity sensitivity 0.5[Formula: text]THz/PU. advantages...
Fano resonance, which is characterized by an asymmetric line shape, arises from interference between the broad and narrow band resonances. The development of metamaterials provides another route for realization resonance. One way to realize resonance use micro-structure, such as wire pair. In pair, dipole quadrupole interferes, resulting in
