Abstract :
III-V based MOSFET for future electronics have received much attention for their potential in future high speed electronics. The mechanisms of charge trapping and detrapping in III-V MOSFET are still yet to understand. Here we investigate an epitaxial La2O3/GaAs heterostructure by pulsed method at cryogenic temperatures, with a focus on the time dependent and temperature dependent charge trapping behavior. In particular, we directly observed the trap freezing at lower temperatures.
