Abstract(in English) | An extremely high transconductance g_m of 2.25S/mm and a cutoff frequency f_T of 310GHz was achieved at a cryogenic temperature (16K) in a 195-nm-gate In_<0.75>Ga_<0.25>As/In_<0.52>Al_<0.48>As high electron mobility transistor (HEMT) with (411)A super-flat interfaces (effectively atomically flat heterointerfaces over a wafer-size area). In this contribution, we investigated dc and radio frequency (RF) characteristics at 300K and 16K for the In_<0.75>Ga_<0.25>As/In_<0.52>Al_<0.48>As HEMTs fabricated on the (411)A- and conventional (100)-oriented InP substrates to clarify the impact of heterointerface flatness on device performance. |
