Investigation on the performance testing technology of nanowire array thermoelectric materials

Nanowire array thermoelectric materials possess high thermoelectric transfer efficiency, so they are very suitable for making micro-cells with microwatt power output. Since their thicknesses are only in the range of ten to several tens of micrometers, the normal testing technology cannot be used. We developed a new technology to test the thermoelectric performance. Based on this new technology, a new measuring system has been built up.
