Title: Cubic SnGe nanoalloys: beyond thermodynamic composition limit

Abstract

A general synthetic route is reported leading to cubic phase Sn x Ge 1−x alloy nanocrystals with a composition varying from essentially pure Ge to 95% Sn. Overcoating of alloys with a sulfide layer increases their thermal stability to 500 °C and makes the alloy nanocrystals amenable to easy ligand exchange.
