Abstract :
For the first time selectivly doped AlInAs/GaInAs heterostructures lattice-matched to InP were successfully grown by MOCVD. Mobility as high as 10500 cm2/Vs (ns=2.7Ã1012cm-2) was obtained at room temperature. We fabricated a HIFET (heterointerface FET) 1.5 ¿m in gate length using the heterostructure, and it showed a transconductance of 302 mS/mm.
