Popis: 0.2 μm T-gate MODFETs have been fabricated and characterized in a planar-doped, lattice-matched InAlAs/InGaAs/InP heterostructure. Extrinsic dc tranconductance as high as 704 mS/mm with very good pinch-off characteristics have been obtained in these depletion-mode devices. A unity current gain cut-off frequency, f T , of 170 GHz is reported for 100 μm-wide MODFETs. This is the highest f T ever reported for MODFETs with this gate length in any material system.
