Abstract

The tenfold increase in electron saturated drift velocity at high electric fields in the AlGaAs/GaAs MODFET channel with InAs inserted layers containing quantum dots (QDs) in a GaAs quantum well is observed. The maximal drift velocity exceeding 108 cm/s is obtained. The maximal current density and transconductance of the MODFET with QDs increasing up to 35 A/cm and 103 mS/mm, respectively, are observed.
