Paper Title:
Combinatorial Pulsed Laser Deposition and Thermoelectricity of (Ca1-xAx)3Co4O9 (A: Sr, Ba) Composition-Spread Films
  Abstract

(Ca1-xAx)3Co4O9 (A: Sr, Ba) composition-spread films were fabricated successfully on TiO2 (100) substrate by combinatorial pulsed laser deposition (CPLD), and their thermoelectric (TE) properties and structure were evaluated by the multi-channel thermoelectric measurement system and concurrent X-ray analysis respectively. The largest power factor in (Ca1-xSrx)3Co4O9 film library was achieved as 1.67µW/cmK2. The influence of substitution on TE properties was investigated by doping Sr2+ and Ba2+ ions into Ca3Co4O9. However, there was little change of Seebeck coefficient in the range of 0≤x≤0.1 for (Ca1-xAx)3Co4O9 (A: Sr, Ba) films, which suggested that the substitution ions with smaller size were potential candidates for good TE properties.
