Abstract
Hole transport properties have been improved by using highly strained In0.35Ga0.65As channel double-modulation-doped heterostructures grown by molecular beam epitaxy. This structure provided both a high mobilit y of 354 cm(2)/(V s) and a high sheet hole concentration of 1.23 x 10( 12) cm(-2) at room temperature. Double-modulation-doped field effect t ransistors with a 0.4-mu m gate length and a 20-mu m gate width were f abricated. Transconductance of 118 mS/mm, which is about 1.5 times hig her than that of single-modulation-doped field-effect transistors, was obtained at room temperature.
