中文摘要	fourier transformation (ft) has been used in the theoretical line shape analysis of franz-keldysh oscillations (fkos) in detail by numerical simulations. fkos from the surface-intrinsic-n(+) gaas structure were obtained in photoreflectance (pr) measurements with various modulation light intensities and with different strengths of bias light illumination, which were used to change the static electric field in the intrinsic layer of the sample. the ft spectra of the pr spectra, including the real part, imaginary part, and the modulus, were very consistent with the theoretical line shapes. the ratio of the square root of the reduced mass (root mu (l)/root mu (h)) and the ratio of transition strength of the electron heavy hole to the electron light hole were obtained from the pt spectra. in addition, the electric field in the intrinsic layer of the sample without and with bias illumination and the modulation field induced by photomodulation were also obtained.
