Stacked elemental layers of Mo/Cu/Sn and Mo/Cu/Sn/Se were employed as samples for investigating the formation reaction of Cu-Sn intermetallic compounds as well as CuSnSe phases by in situ technique of X-ray diffraction and differential scanning calorimetry. The use of a combined in situ technique allows a real-time observation on solid-state reactions as well as any crystalline phase changes during annealing towards the crystallization of CuSnSe. It is found that Cu and Sn form intermetallic compounds of CuSn, CuSn and CuSn as the annealing temperature rises from 30 to 550 C. The reaction of Se with Cu to form a CuSe phase dominates the binary phase formation at a low annealing temperature. The annealing of a stacked Mo/Cu/Sn/Se layer suggests that only CuSn intermetallic compound directly acts as a reactant for the Cu-selenide phase formation. A SnSe phase mostly forms from a liquid-state reaction of Sn and Se above the Sn melting point. The in situ investigation also reveals a complete set of Cu-selenide peritectic decompositions of CuSe → CuSe → CuSe at 360 and 412 C. The formation of CuSnSe phase starts at 450 C as a product from a reaction between Cu Se and SnSe in a presence of liquid Se. Comparisons on the initial formation temperatures of all involved phases and on the formation pathways between CuSnSe and CuSnS are discussed as well. © 2013 Elsevier B.V. All rights reserved.
