Effect of In incorporated into SbTe on phase change characteristics resulting from changes in electronic structure

The effects of the In content of InSbTe films with various stoichiometries (⁠ Sb 2 Te 2.7⁠, In
0.5 Sb 2 Te 2.9⁠, and In 2.6 Sb 2 Te 2.9⁠) on phase change characteristics were
investigated. With increasing incorporation of In atoms into Sb 2 Te 3⁠, various crystalline
phases, ie, In 2 Te 3⁠, Sb, and In 3 SbTe 2⁠, were observed due to the bond energy
between the constituent atoms, while only Sb 2 Te 3 and the Sb 2 Te 2 phases were
observed in the case of Sb 2 Te 2.7 and In 0.5 Sb 2 Te 2.9 films. In addition, the shifts in …
