摘要：
The Debye-Waller factors obtained by EXAFS analysis of the Te nanoparticles are analyzed by a Einstein model. The Einstein temperatures for the intra-and interchain interactions are depend on the size of the Te nanoparticles. With decreasing the size of the Te nanoparticles the Einstein temperature for the intrachain correlations increases, while that for the interchain correlations decreases. The value of the static components of the Debye-Waller factors for both the intra-and interchain correlations increase with decreasing of the size. The reduction of the interchain interactions for the Te nanoparticles would induce the increase of the Einstein temperature for the intrachain correlations and the decrease of the interchain correlations.
