Construction of a thermal conductivity measurement platform for bulk and thin film materials based on the 3-Omega technique

Nanostructured materials show signicant enhancement in the thermoelectric g-

ure of merit (zT) due to quantum connement eects. Improving the eciency of

thermoelectric devices allows for the development of better, more economical waste

heat recovery systems. Such systems may be used as bottoming or co-generation

cycles in conjunction with conventional power cycles to recover some of the wasted

heat. Thermal conductivity measurement systems are an important part of the char-
