<p><P>PROBLEM TO BE SOLVED: To provide a thermoelectric conversion element including characteristics of high electromotive force, high electrical conductivity and low thermal conductivity, thereby having high figure of a merit of a thermoelectric conversion element. <P>SOLUTION: A thermoelectric conversion element is formed by: forming a strontium titanate thin film buffer layer 11 which is doped with niobium or lanthanum and has a nonconducting anionic nonstoichiometric composition, on a single crystal substrate 9 of strontium titanate; and forming a strontium titanate thermoelectric thin film which is doped with niobium and lanthanum and has a stoichiometric composition, or a strontium titanate thermoelectric thin film 12 which is doped with niobium and lanthanum and has a nonstoichiometric composition, on the thin film buffer layer 11. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
