High temperature vulcanized (HTV) silicone rubber (SiR) is widely used as HVDC cable accessory insulation considering its outstanding electrical properties along with elasticity and thermal resistance. However surface charge caused by corona would accumulate on SiR surface and distort the local field which in consequence led to accessory premature discharge and insulation failure. This paper tried...
The addition of silicon carbide (SiC) micro powder into silicone rubber (SiR) matrix has been found to introduce a marked nonlinear conductivity into the resulting composites, without a degradation of the insulating properties under low electric field. Owing to these properties, the SiR-based nonlinear conductive composites have a potential use as the field grading material (FGM) layer in high voltage...
We investigate terahertz (THz) radiation from 6H- and 4H-SiC photoconductive (PC) antennas excited at 400 and 800 nm wavelengths. We demonstrate that 6H-SiC large aperture PC antennas have the potential to generate sub-MV/cm THz fields.
Studies of strong terahertz (THz) electroluminescence in several SiC natural superlattices allowed us to reveal changes in the emission spectra, which are in well consistency with the theory of electron Bloch oscillations, and to discover new channels of intensive THz electroluminescence.
