(a) Prospective view of the average structure model KT used in the fitting procedure. It presents an ideal 50% intermixing with Ge atoms in the Sb layer in front of the QLs. (b,c) Close-up of the dashed zone in panel (a) with highlighted distances relative to the 1st and 2nd shells, respectively. In particular, the marked Sb and Ge atoms represent the different absorber inequivalent positions A, B and C.
