Zinc telluride under high pressure: An x-ray absorption study

Abstract
The local structure of ZnTe has been studied up to 30 GPa by x-ray absorption spectroscopy at the Zn K-edge. Phase transitions were observed at 9.5±0.5 and 12.±0.5 GPa. From the EXAFS and XANES studies it is deduced that ZnTe-II has as tetrahedral structure and ZnTe-III a distorted octahedral. A first order Mumaghan equation of state has been fitted to the first neighbors distances in phase I, giving a bulk modulus of 56 GPa.
