The thermal conductivity of silicon | Electronics Cooling
For steady state thermal analyses at the board and system level, however, accurate values are not required, because the influence of the Silicon on the overall performance is limited. Remarkably, the thermal conductivity (in W/mK) defined in various papers and handbooks varies widely – 68.8, 83.7, 100, 125, 140, 153.46!, 157 – and often only one value at an unknown temperature is recommended.
Silicon Carbide: A Tug-Of-War - EE Times India
Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
