Preparation and thermoelectric properties of sulfur doped Ag2Te nanoparticles via solvothermal methodsElectronic supplementary information (ESI) available. See DOI: 10.1039/c2nr30469d

In this work, n-type Ag 2 Te nanoparticles are prepared by a solvothermal approach with uniform and controllable sizes, e.g. 5-15 nm. The usage of dodecanethiol during the synthesis effectively introduces sulfur doping into the sample, which optimizes the charge carrier concentration of the nanoparticles to >1 × 10 20 cm −3 . This allows us to achieve the desired electrical resistivities of
