摘要：
In this study, we synthesized Ag2Te nanoparticles (NPs) in an aqueous solution and investigated the thermoelectric characteristics of Ag2TeNP thin films on bendable substrates. The Ag(2)TeNPs have an average size of 6 nmand a body-centered cubic gamma-phase (or, gamma-Ag2Te), and they exhibit typical p-type thermoelectric behaviors. The Seebeck coefficient and electrical conductivity of a gamma-Ag2TeNP thin film are 1330 mu V/K and 0.037 S/m, respectively, and the power factor is calculated to be 0.66 mu W/mK(2). Furthermore, our bending study shows the stability of the thermoelectric characteristics of gamma-Ag2Te NP thin films after the bending cycles. (C) 2017 Elsevier B.V. All rights reserved.
