Conductivity Behavior

In this work the results of an experimental study of Fe2Ti1-xVxSn alloys (x = 0; 0.06; 0.15; 0.2) are presented. According to the temperature dependencies of the electrical conductivity, Seebeck coefficient and thermal conductivity, it is established, that the studied compositions exhibit transport properties typical for semiconductors. The substitution of V at the Ti site leads to a change of the p-type electrical conductivity behavior to n-type; the pristine sample of Fe2TiSn has the best thermoelectric properties.

SixGe1-x (x = 0.75 for n-type and 0.7 for p-type) is a typical thermoelectric material used at higher temperature as thermoelectric generator. Its property is dependent on the composition. SixGe1-x containing different amount of fullerite added as hollow quantum dot were fabricated by hot-pressing method. The relations among thermoelectric property, the amount of fullerite and the microstructure were investigated by normal measurement and analytical method.
