Abstract :
A new HEMT using InAlAs/InGaAs grown on GaAs has been realized. This structure, with an In content close to 27%, presents high electron mobility with high 2DEG density (20700 cm2/V.s with 4×1012cm¿2 at 77K) and high Schottky barrier quality (Vb=0.68V with n=1.1). A 3 ¿m gate length device has shown intrinsic transconductance as high as 530 mS/mm.
