Аннотация: In situ transmission electron microscopy investigations of the processes of solid-state synthesis and atomic ordering in bilayer Cu/Au nanofilms (atomic ratio, Cu : Au = 3 : 1) are conducted. It is found that solid-state synthesis starts at 170°C. A Cu 3Au atomic-disordered structure (Fm3m space group; lattice con- stant, a = 3.76 Показать полностью± 0.01 A) forms at 280°C. Annealing the film for 1 hour at 380°C produced a Cu 3AuI (L1 2 type) atomic-ordered superstructure, a Pm-3m space group, and lattice constant, a = 3.76 ± 0.01 a in the bulk of the film. © Allerton Press, Inc., 2012.
