摘要：
The time evolution of oxygen stoichiometry profiles in Fe-doped SrTiO3 single crystals has been detected and analyzed in-situ using an optical absorption technique. The profiles can be fitted according to Fick's second law by a constant chemical diffusion coefficient. The data obtained are in good agreement with earlier results from integral detection techniques and can be quantitatively understood by including the influence of internal coupling reactions to bare ambipolar transport via short range interaction.
