Silicon Carbide Heating | Sim-cdm

silicon carbide that is classed as an excess electron type semiconductor. The electrical resistance of a SiC resistor is difficult to measure at room temperature due to minor impurities, self heating, and contact resistance. Also the green silicon carbide has a negative resistance temperature characteristic from room temperature to approximately 1200°F (650ºC).

Piezoresistive effect - Wikipedia

History. The change of electrical resistance in metal devices due to an applied mechanical load was first discovered in 1856 by Lord Kelvin.With single crystal silicon becoming the material of choice for the design of analog and digital circuits, the large piezoresistive effect in silicon and germanium was first discovered in 1954 (Smith 1954).
