Effect of annealing temperature on the thermoelectric properties of ZnInO thin films grown by physical vapor deposition

Enhanced Thermoelectric Properties of Skutterudite Thick Film Polyvinyl Alcohol Assisted from the Post-Deposition Annealing Effect

“…Meanwhile, the thicker film strategy can be combined with the post-deposition annealing treatment which commonly employed to improve the film's crystallinity [25][26][27] that induces grain size and boundary changes, hence influence the charge carrier concentration and charge mobility. 28 The grain boundaries modification also promotes phonon scattering thus increase S and simultaneously reduce κ of thermoelectric material. Such observation was reported shows improvement of the power factor, PF from 7 × 10 −5 to 4 × 10 −4 Wm −1 .K −2 as the annealing temperature was increased up to 400 °C and leading to remarkable low κ values (< 10 Wm −1 K −1 ).…”
