Abstract
CuBO2 is prepared by a solid-state reaction method to investigate thermoelectric properties in high temperature. The XRD result confirms the CuBO2 compound existing in this method. The Seebeck reveals the compound displays p-type thermoelectric material. The experimental results of electrical resistivity exhibited results of 0.004 S/cm to 0.038 S/cm with the temperature range of 650 to 830 K. The Seebeck value is in the range of 450 μV/K to 950 μV/K, and the thermal conductivity is in the range of 1.4 × 10-5 to 5.3 × 10-5 W/m-K2 with the same temperature. The maximum PF and ZT is 5.3 × 10-5 W/m-K2 and 0.0016, respectively, at 960 K. This work demonstrates that the CuBO2 delafossite-oxide compound displays the p-type thermoelectric materials. © 2014 IEEE.
