摘要：
The Debye-Waller factors obtained by EXAFS analysis of the trigonal Te (t-Te) and the Te nanoparticles are analyzed by a Debye model. In t-Te the Debye temperature (Theta(D)) of the intrachain interactions is about two times higher than that of the interchain atomic interactions. The Theta(D) for the intrachain interactions of the Te nanoparticles is higher than that of t-Te, but Theta(D) for the interchain interactions of the Te nanoparticles is lower than that of t-Te. The reduction of the interchain interactions for the Te nanoparticles would induce the change of the Debye temperatures.
