Influence of polarization coulomb field scattering on the subthreshold swing in E-mode p-GaN/AlGaN/GaN HEMTs

Influence of polarization coulomb field scattering on the subthreshold swing in E-mode p-GaN/AlGaN/GaN HEMTs

In the present study, p-GaN/AlGaN/GaN HEMTs treated with hydrogen plasma passivation were fabricated. Capacitance–voltage (C-V) and current–voltage(I-V) characteristics of these devices were subsequently measured. The relationship between polarization Coulomb field (PCF) scattering and the subthresh...
