Processing and Characterization of Silicon Carbide (6H

Silicon carbide is a promising wide bandgap semiconductor material for high-temperature, high-power, and high-frequency device appliions. However, there are still a nuer of factors that are limiting the device performance. Among them, one of the most important and critical factors is the formation of low resistivity Ohmic contacts and high

Highly effective anti-corona coatings on aluminium wires

XRD-s of SiC and AlSi were obtained in the deposited coatings for all test samples which can be explained due to the presence of Si in the sodium salt Na 2SiO 3 (sodium metasilie) in the main electrolyte. Analysis of EDS-, XRF- and XRD-spectra shows that the main compounds that makes up the coatings are Al 2O 3, SiO 2, AlSi and SiC.
