Ionic and Electronic Transport in Ag2S Nanocrystal–GeS2 Matrix Composites with Size-Controlled Ag2S Nanocrystals

Authors


Abstract

Ag2S nanocrystals (NCs) are embedded into a GeS2 matrix while controlling the size, shape, and interparticle spacing of the Ag2S NCs. We demonstrate that the ionic and electronic properties of these inorganic nanocomposites can be systematically controlled by varying the diameter of the Ag2S NCs. We also observe an ionic conductivity enhancement relative to pure Ag2S and (GeS2)0.5(Ag2S)0.5 glass.
