Abstract
γ- In 2 Se 3 thin film are deposited for various substrate temperatures in the range of 523–673 K. This study shows that at 573 and 673 K the thin films are well crystallized with grains aligned along the c axis. Between these temperatures, a domain of instability appears where the γ-In2Se3 thin films have a randomly orientation and the c-lattice parameter increases. The presence of the metastable phase κ-In2Se3, during the growth, can explain the existence of this domain of instability. The insertion of Zn during the preparation process allows us to stabilize the phase κ at room temperature which confirms our hypothesis that the presence of κ-In2Se3 perturbs the crystallization of γ-In2Se3. The increase of the c-lattice parameter can be explain by the fact that κ-In2Se3 has a larger unit cell than γ-In2Se3 or by a competition during the growth between the grains of both phases which could generate constraints along the c axis. During the cooling, the κ phase disappears in favor of the γ phase.
