(a) The γ factor around the In and As K-edges as functions of α and θ (see details in Table S1 to S2). (b) The α-dependences of the γ effects on the EXAFS amplitudes (Calc.) and of As Kα/Ga Kα for the GaAs wafer (Exp.). The full red circle is the result from As Kα. The oval trace indicates the region where the γ effect is small but the SA effect is large. Insert: experimental geometry. |
