- W320244227 abstract "Abstract : The gate current of Al27Ga73N/GaN heterogeneous field effect transistors (HFETs) is investigated using current-voltage (IV) and current-temperature (IT) measurement demonstrating that trap assisted tunneling (TAT) is the primary current mechanism. A thermionic trap assisted tunneling (TTT) model is used with variables of Schottky barrier height, trap energy, donor density and trap density. This results in a sigma of 1.38x10^(-8) A for IT data measured between 85K and 290K and for IV data measured between 0.0 V and -4.0 V. High energy (>0.5 MeV) neutron irradiation confirms an increase of gate current with fluence. An increase in magnitude of threshold voltage is also observed. The TTT model suggests that increased trap density is responsible for increased gate current at a fluence of 1.2x10^12. An increase in trap density from the unirradiated fit value of 4.593x10^21 to 5.737x10^21 traps/m^3 and an increase in the position of traps in the energy band from 0.896 to 0.9028 V results in a fit with σ of 1.77x10^(-9) A. An increase in donor defect density is modeled resulting in a sigma of 5.00x10-9 A and an increase in threshold voltage magnitude consistent with the observed change in measured IV behavior." @default.
