High-Voltage Silicon-Carbide Thyristor with an n -type …

The possibility of creating a high-voltage SiC thyristor with an n-type blocking base is analyzed.It is shown that a thyristor structure fabried as an “analog” of a modern thyristor structure with a p-type blocking base, i.e., with the same layer thicknesses and replaced doping types (donors instead of acceptors, and vice versa), cannot be turned-on at any input signal level.

Materials | Free Full-Text | Decreasing Resistivity of …

Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the

Octagonal cell topology for high-frequency silicon …

The n- and p-type regions were created using ion implantation of nitrogen and aluminium, respectively. The resultant doping was activated using 1650°C annealing with a carbon cap. Dry oxidation at 1175°C was used for the 50nm gate insulator.

"Simultaneous Ohmic Contacts to n and p-type Silicon …

The paper explores possible metallization schemes to form simultaneous ohmic contacts to n-type and p-type silicon carbide contacts. Silicon carbide has shown promise in revolutionizing the power electronics market due to its increased switching speed, compact design, and higher temperature tolerance when compared to Silicon, the market standard. With the continuing development of silicon
