(a) Geometry of the sample and the solid-state detector (SSD) for measuring the angle dependence of the fluorescence and scattered X-rays. The SSD makes an angle θ with the polarization vector of the incident X-ray beam. (b) Angle dependence of the fluorescence (white circles), X-ray resonant Raman scattering (squares) and elastic scattering intensity (black circles) from an Er-doped GaAs sample. The incident X-ray energy was fixed at 8.790 keV. |
