Abstract

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 (⊖_D) of the intrachain interactions is about two times higher than that of the interchain atomic interactions. The ⊖_D for the intrachain interactions of the Te nanoparticles is higher than that of t-Te, but ⊖_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.
