T1 IN-SITU STUDY OF SOLID-PHASE CONVERSIONS IN A TWO-LAYER FILM Cu/Se NANOSTRUCTURE JF Nanoscience and Technology: An International Journal JO NST YR 2011 FD 2011-05-10 VO 2 IS 1 SP 55 OP 60 K1 two-layer film nanostructure K1 solid-phase reaction K1 energy of elastic deformation K1 relaxation K1 diffusion AB Experimental results of the in-situ study of solid-phase interaction of Cu and Se nanolayers deposited on glass substrates are presented. It is found that the lead time of solid-phase reactions in a two-layer film Cu/Se nanostructure strongly depends on the thickness of the selenium film. When the Se film has a thickness of 90 nm the solid-phase reaction is completed in 16 s, and with a thickness of 140 nm it is completed in 4 s. It is found that diffusion of Cu into the Se layer is observed at a Se film thickness of 140 nm and the avalanche-like solid-phase reaction with the formation of hexagonal CuSe (lattice parameters: a = 3.939 Å, c = 17.25 Å) is initiated.
