| Abstract: | The carrier concentration and effective mass of mesoporous SrTiO3 films were controlled by the substitution of Ti with V-group elements (V, Nb, and Ta) to enhance the thermoelectric properties. We calculated the effect of the substitution on the effective mass of SrTiO3 by analyzing its structural and electrical properties. When V was used as a substitute, the effective mass increased slightly due to a small change in the V | |
