In order to enhance the electron mobility we use step graded channel structure in the heterostructure field effect transistor to reduce Coulomb scattering. The electrons are far away from the AlGaAs/InGaAs interface. We fabricated successfully and ob

A heterostructure field-effect transistor with a step-graded channel has been successfully fabricated. The conduction electrons are distant from the AlGaAs/InGaAs interface; thus the Coulomb scattering is reduced, and consequently, electron mobility
