| Popis: | In this letter, N2 and forming gas (FG) were used during ohmic contact annealing of InAlN/GaN HEMTs on Si. It is found that N2 annealing offers lower ohmic contact resistance (RC) while FG annealing features lower sheet resistance (Rsheet). Then FG/N2 two-step annealing was used to achieve a subthreshold swing (SS) of 113 mV/dec, an on/off current (Ion/Ioff) ratio of ~ 106, a transconductance (gm) peak of 415 mS/mm, a record low drain-inducing barrier lowing (DIBL) of 65 mV/V, and a record high power gain cutoff frequency (fmax) of 270 GHz on 50-nm InAlN/GaN HEMT on Si. Comment: 13 pages, and 4 figures |
