Notes:
Using the digital alloy technique, a series of high-mobility remotely doped GaAs/AlGaAs coupled multiple quantum well structures have been produced by the superposition of a wide parabolic quantum well and a square superlattice potential. Structures containing up to twenty superlattice periods with low temperature Hall mobilities from 23 000 to 100 000 cm2/V s have been produced. Fourier analysis of low field Shubnikov–de Haas oscillations, capacitance-voltage and Hall measurements of a 200 A(ring) period superlattice in a 1600 A(ring) wide parabolic well indicate the occupation of four superlattice periods with subband spacings in good agreement with theory.
