We have used electrochemical anodic oxidation to form gate oxides on strained n-channel Si:SiGe quantum wells. The oxides are characterized by current-voltage and capacitance-voltage measurements. Comparison of measured and calculated electron sheet densities in the quantum well, indicates that the oxide growth does not cause degradation of the Si:SiGe material. This is confirmed by low-temperature measurements of the electron mobility and sheet density in the quantum well.
