Alloy scattering-limited mobility is calculated for narrow quantum wells of GaAs/Ga0.7Al0.3As, Ga0.47In0.5As/InP, and Al0.48In0.5As/Ga0.47In0.53As systems with widths down to 0.5 nm, taking into account the energy-band nonparabolicity and the effects of wave-function penetration into the barrier layer. Values of mobility are found to be significantly different from those given by the formulas derived earlier for wide wells.
