Shubnikov-de Haas measurements of the 2-D electron gas in pseudomorphic In(0.1)Ga(0.9)As grown on GaAsShubnikov-de Hass (SdH) measurements performed on a 200 A layer of pseudomorphic In(0.10)Ga(0.90)As grown by MBE on undoped GaAs with an overlayer of Al(0.15)Ga(0.85)As are presented. These measurements were performed in magnetic fields up to 1.4 tesla at T in the range of 1.4-10 K. It was found that only one subband was populated with a density of 5.8 x 10 to the 11/cm-squared and an effective mass at the Fermi level m(asterisk) = (0.060 + or - 0.001)m(0).
