The objective of the present dissertation is to improve the thermoelectric efficiency (ZT) of Ca3Co4O9 metal oxide with a focus on nanostructuring, porosity and elemental substitution altering the electrical and thermal transport properties at high temperature and to establish a unique high temperature Seebeck coefficient and electrical resistivity measurement system. An instrument for the high temperature measurement of Seebeck coefficient and electrical resistivity of one and/or two bulk samples over a temperature range of 300 – 1100 K is designed and implemented in our laboratory. During the installation of the system, five inventions have been made. These are; 1) cold-finger effect eliminated triple beadless thermocouples, 2) magnetic f...
