Abstract
Magnetotransport measurements as a function of B-field orientation are studied on p-type strained-layer (001) GaAs/As/GaAs quantum wells at temperatures from 4.2 to 0.4 K. It is shown that the two-dimensional holes are derived from the =±3/2 subbands and that the Zeeman splitting between the =3/2 and =-3/2 states of the same Landau level depends on the components of B perpendicular to the strained layer and not the total B. This g-factor anisotropy is shown to be a consequence of the large uniaxial strain in the As layer.
