  • Abstract
    A fully quaternary In0.52(Al0.8Ga0.2 )0.48As/In0.53(Al0.2Ga0.8 )0.47As heterostructure was introduced into doped-channel FETs (fully-Q DCFETs) on InP substrates for the first time. Combining the advantages of high quality quaternary InAlGaAs Schottky and channel layers, the authors were able to enhance device gate-to-drain and channel breakdown voltages, and to eliminate the kink effect. This results in an extremely low output conductance (g0 =0.6 mS/mm), and a high DC gain ratio (gm/g0≃350)
