摘要
High-performance 0.15 mum gate length modulation-doped field-effect transistors (MODFETs) have been fabricated on a lattice-matched InAlAs/InGaAs heterostructure grown by organic vapour phase epitaxy (MOVPE). Excellent 'kink-free' DC characteristics with extrinsic transconductance g(m) of 1080 mS/mm at a drain current of 508 mA/mm have been achieved. A unity current-gain cutoff frequency f(T) of 187 GHz at room temperature has been measured, which is the highest value reported for MOVPE-grown lattice-matched InAlAs/InGaAs MODFETs.
