Ss. Lu et Cl. Huang, PIEZOELECTRIC FIELD-EFFECT TRANSISTOR (PEFET) USING IN0.2GA0.8AS AL0.35GA0.65AS/IN0.2GA0.8AS/GAAS STRAINED-LAYER STRUCTURE ON (111)B GAAS SUBSTRATE/, Electronics Letters, 30(10), 1994, pp. 823-825
A novel electronic device using a two dimensional electron gas produce
d by the strain-induced electric field in a [111] growth-axis In0.2Ga0
.8As/Al0.35Ga0.65As/In0.2Ga0.8As/GaAs strained layer structure without
modulation doping is reported. Two dimensional electron gas densities
greater than 10(11)cm-2 were observed both at room temperaure and 77-
degrees-K. A field effect transistor using this strain-layer structure
was fabricated successfully.
