The density and mobility of the electrons in the sheet are critical for the operation of the HEMT. HEMTS consisting of AlGaN/GaN/Si are being studied because they promise better performance at higher powers, temperatures, and frequencies than conventional silicon HEMTS can achieve. In one study, the Hall effect was used to measure the density of electrons in one of these new HEMTs.
