| 英文摘要 | Interfacial diffusions and/or chemical reactions are one of the key issues for the reliability of CoSb3-based skutterudite thermoelectric (TE) joint, especially for the p-type joint, which limits the applications of TE devices. We investigate the interfacial evolution for p-type CeyFexCo4-xSb12/Nb joints (y = 0.5-1, x = 2, 3, 4) and combine the previous study on n-type Yb0.3Co4Sb12/Nb joint to demonstrate the effect of TE materials on the interfacial microstructure and interfacial resistivity. The reaction-diffusion kinetic analysis shows that the TE materials has little effect on chemical reactions but strongly influence the Sb diffusions. The low energy barrier of Sb diffusion leads to the absent phase decomposition of skutterudites in CeyFexCo4-xS12/Nb joints. The interfacial resistivity of CeyFexCo4-xS12/Nb joints is related with Fe content and the interfacial reaction layer (IRL) growth. In addition, since the interfacial reaction layer growth rate and interfacial resistivity of CeyFexCo4-xS12/Nb joints are both low, Nb is an adequate barrier layer candidate material. |
