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. 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. diamond texture for substance painter
