| 英文摘要 | CuGaTe2 based composites incorporated with graphite nanosheets (GNs) CuGaTe2/x G (G = GNs, 0 <= x <= 3.04 vol.%) were prepared, and the thermoelectric properties of the composites were studied from 300 to 875 K. The results show that the incorporation of GNs into the CuGaTe2 matrix can enhance the Seebeck coefficient and power factor over the whole temperature range investigated due to energy filtering effects, and the reduction of thermal conductivity below 750K owing to interface scattering. Although the resistivity increases, energy filtering significantly raises the Seebeck component, and the overall effect on power factor is positive. The sample with 2.28 vol.% GNs had the largest ZT value, reaching 0.93 at 873 K, which is a similar to 21% improvement on pure CuGaTe2. (C) 2016 AIP Publishing LLC. |
