Before revision: Advantages Advantages of HEMTs are that they have high gain, this makes them useful as amplifiers; high switching speeds, which are achieved because the main charge carriers in MODFETs are majority carriers , and minority carriers are not significantly involved ; and extremely low noise values because the current variation in these devices is low compared to other .
