WebThe thermal conductivity of GaAs is related to the temperature of the material over a wide temperature range and varies approximately as 1/T, where T is the temperature in … Web(CTE) between the die and the mounting surface. MMICs will crack if there are large differences in expansion between the materials. Often MMICs are mounted on pedestals which are made of kovar, molybdenum, or silicon, because these materials closely match the expansion of GaAs (~7ppm/ºC), and are good thermal conductors.

WebMar 1, 2016 · GaAs is a direct bandgap semiconductor material which results in lower charge-carrier lifetime, due to direct (radiative) recombination. The lower electron and hole lifetime will results in lower switching losses. Therefore for GaAs bipolar diodes, low switching losses combined with low conduction losses can be expected.
