Epitaxial Stabilisation of $\mathrm{G}{\mathrm{e}}_{1-\mathrm{x}}\mathrm{S}{\mathrm{n}}_{\mathrm{x}}$ Alloys

Alfonso Sanchez-Soares, Conor O'Donnell, James C. Greer

The thermodynamic stability of germanium tin $\mathrm{G}{\mathrm{e}}_{1-\mathrm{x}}\mathrm{S}{\mathrm{n}}_{\mathrm{x}}$ alloys is investigated across the composition range $0\le x\le 1$ by applying density functional theory (DFT)…
