(a) q-DAFS spectrum of the (006) reflection of a GaAsP film, measured in 4 min using the feedback control described in §3.1. (b) EDAFS of the (006) reflection of the GaAsP file, normalized to Is. (c) q-DAFS spectrum of the (006) reflection of a GaAs substrate, with the feedback control. The FWHM of the substrate peak was 0.008°. Insets show the signal quality in terms of sampling (0.05 eV step) and signal-to-noise ratio. |
