Investigation of the Atomic Structure of Ge-Sb-Se Chalcogenide Glasses

Figure 3

Partial atom pair correlation functions, (r) for the Ge₄₀Se₆₀ (black square), Ge₃₅Sb₅Se₆₀ (red circle), Ge₃₂Sb₈Se₆₀ (blue triangle), Ge₂₇Sb₁₃Se₆₀ (green crosses), Ge₂₀Sb₂₀Se₆₀ (orange square), and Ge₁₅Sb₂₅Se₆₀ (purple reverse triangle) compositions, obtained by RMC modeling of the Ge-Se (a), Sb-Se (b), Ge-Sb (c), Ge-Ge (d), Sb-Sb (e), and Se-Se (f) atom pairs. For better clarity, the curves are shifted vertically.
