Abstract: Ruddlesden-Popper type compounds, being presented as (ABO3)n-AO or An+1BnO3n+1 (n=1, 2, 3…∞), have a layer structure where perovskite layer ABO3 and rock salt type layer AO are alternately in place; Can+1(Mn1-xVx)nO3n+1 (0≤x≤1) belongs also to this compound. As CaO layer shows low thermal conductivity whereas CaMnO3 layer reveals high electrical conductivity and high Seebeck coefficient, therefore, Can+1(Mn1-xVx)nO3n+1 seems to become a promising module as a thermoelectric conversion material. However, there was no report concerning about the thermoelectric conversion characteristic of this compound. In this study we have investigated electrical conductivity, Seebeck coefficient, and thermal conductivity of Can+1(Mn1-xVx)nO3n+1 and discussed about the possibility of the application as thermoelectric conversion elements from dimensionless performance index ZT.
