Abstract

Addition of In and Ag into eutectic Sb ₇₀Te ₃₀ fast-growth material was studied. We explored the optical transitions and crystallization kinetics of Sb ₇₀Te ₃₀ and Ag ₃In ₅Sb ₆₀Te ₃₂ recording films. The results showed that Ag ₃In ₅Sb ₆₀Te ₃₂ has a higher crystallization temperature but a similar melting point compared to Sb ₇₀Te ₃₀. In both the crystalline and amorphous states, addition of Ag and In increased the refractive index and decreased the extinction coefficient of Sb ₇₀Te ₃₀Ag ₃In ₅Sb ₆₀Te ₃₂ has better thermal stability and a lower crystallization speed than Sb ₇₀Te ₃₀film.
