(a) The z = 0.97 Å layer in the 3D-ΔPDF which is the slice closest to the z component of the inter-sublayer orderings between the Cu1a and Cu1b sublayers in Cu1.95Se. (b) The inter-sublayer order of the Cu1a and Cu1b sublayers. The blue-toned atoms mark the occupied sites in the lower sublayer while the red-tinted atoms mark the occupied sites in the upper sublayer. The numbers on the atoms correspond to the location of the atom relative to the origin of the 3D-ΔPDF. The intensity is on an arbitrary scale. |
