Abstract

Studies of Shubnikov-de Haas (SdII) oscillations corresponding to the spin-Landau levels of a two-dimensional electron gas at 100 mK have been performed on modulation-doped n-type Si/Si1-xGex heterostructures. The method used to obtain the effective Landé g-factor can be described as the method of coincidences, where the tilt angle that causes adjacent Shubnikov-de Haas (SdII) minima to be equal is used to determine the effective g-factor. The effective g-factor for 6⇔8 was 3.34±0.05. The results demonstrated that the effective g-factor oscillated as a function of the filling factor.
