Abstract :
Data is reported from 180 nm gate length GaAs n-MOSFETs with drive current (Ids,sat) of 386 μA/μm (Vg=Vd =1.5 V), extrinsic transconductance (gm) of 426 μS/μm, gate leakage ( jg,limit) of 44 nA/cm2, and on resistance (Ron) of 1640 Ω μm. The gm and Ron metrics are the best values reported to date for III-V MOSFETs, and indicate their potential for scaling to deca-nanometre dimensions
