A Schottky-barrier normally off InAlN-based highelectron-mobility transistor (HEMT) with selectively etched access regions, high OFF-state breakdown, and low gate leakage is presented. Metal–organic chemical vapor deposition-grown 1-nm InAlN/1-nm AlN barrier stack is capped with a 2-nm-thick undoped GaN creating a negative polarization charge at a GaN/InAlN(More)
Hot-electron temperature (Te) in InAlN/GaN highelectron-mobility transistors (HEMTs) was determined using electroluminescence spectroscopy as a function of gate voltage and correlated with the Te distribution determined by hydrodynamic simulations. Good agreement between measurement and simulations suggests that hot electrons can locally reach temperatures(More)
