Phemt switching time

HEMTs are heterojunctions. This means that the semiconductors used have dissimilar band gaps. For instance, silicon has a band gap of 1.1 electron volts (eV), while germanium has a band gap of 0.67 eV. When a heterojunction is formed, the conduction band and valence band throughout the material must bend in order to form a continuous level. The HEMTs' exceptional carrier mobility and switching speed come from the following conditions… pHEMT technology has matured since its invention and has demonstrated outstanding reliability over the course of its evolution. pHEMT devices routinely pass High Temperature Operating Life Tests (HTOL) at a junction temperature (Tj) of 150℃ over 1000 to 5000 hours.
