摘要：

The possibilities given by XAS for structural determination under extreme conditions are discussed through the example of HgTe which exhibits three phase transition below 20 GPa. All of the structures have been determined or corroborated using EXAFS analysis and XANES simulations. Pressure induced amorphization (berlinites) or crystallization (amorphous Ge and liquid Kr) can be followed by XAS before and after the transition. Future developments related to the new generation of synchrotron radiation sources are presented.
