Figure 3 The 3D-ΔPDFs of Cu1.95Se from the (a)–(c) in-house and (d)–(f) synchrotron measurements in the (a) and (d) z = 0 Å plane, (b) and (e) the z = 0.97 Å plane and (c) and (f) y = 0 Å plane. The 3D-ΔPDFs are visually identical except for noise near the origin of the in-house 3D-ΔPDF which changes a few of the analysis steps, but it is not detrimental to the analysis (see text). The intensity in each row is on an arbitrary scale. |
