Takashi Mimura: High electron mobility single heterojunction semiconductor devices. Fujitsu, Staas & Halsey, January 3, 1984: US04424525 (125 worldwide citation)

A thin electron accumulation layer is generated along a heterojunction between two kinds of semiconductors each of which has a different electron affinity. This electron accumulation layer suffers less ionized-impurity scattering, because the thickness does not exceed the spread of an electron wave. ...
