However, GaAs is another vital base semiconductor for IMPATT diodes at the both microwave and mm-wave frequencies. Fun Facts about the name Gaas. The MESFET structure is very similar to a junction FET or JFET. While GaAs has a basic power density of about 1.5 W/mm, GaN has a power density ranging from 5 to 12 W/mm. In the Bridgman-Stockbarger method, the crystals are grown in a horizontal zone furnace that allows the gallium and arsenic vapors to react and then the free molecules deposit on a seed crystal cooler at the end of the furnace. The issue of InAs on GaAs is that the surface of InAs is usually rough and that causes a drop in semiconductor performance. Service failures in GaAs devices can occur at surfaces and interfaces, in the substrate or active layers, at Schottky and ohmic contacts, and by EM and corrosion damage of the metallization. As such the Schottky diode is used as a reverse biased diode in the same was that a JFET does. GaAs, GaP etc. Definition from Wiktionary, the free dictionary.
