Abstract
We report the observation of Shubnikov-de Haas oscillations in superlattices of GaInAs and InP, showing evidence of two-dimensional behavior. The electron g-factor is deduced from both the criteria for resolution of a spin splitting by comparison with the broadening parameter Γ, and from the tilted field method, and is shown to increase with increasing resolution of the Landau levels in a manner consistent with the theory of Ando and Uemura. In the ultraquantum limit, structure at ν=1/2 and ν=1/3 is observed.
