Abstract

InAlN/Al/GaN HEMT directly on Si for steep subthreshold slope (<60mV/dec) is demonstrated in this study, and is attributed to displacement charge transition effect. The material analysis with High-Resolution X-ray Diffraction (HR-XRD) and the relaxation by reciprocal space mapping (RSM) are performed to confirm Indium barrier composition and epitaxy quality. The proposed InAlN barrier HEMTs exhibits high ON/OFF ratio with 7 magnitudes and a steep SS is also obtained with subthreshold swing (SS) = 99 mV/dec for forward sweep and SS = 28 mV/dec for reverse sweep.
