| Abstract | The pressure-induced phase transition of bismuth selenide (Bi2Se3) was investigated by combining theoretical calculations with synchrotron powder X-ray diffraction measurements up to 57.4GPa. We demonstrated that the ambient-pressure rhombohedral Bi2Se3 crystallized into a monoclinic structure with the space group C2/m at 9.1GPa, and eventually to a body-centered tetragonal structure with the space group I4/mmm at about 27.2GPa. This behavior was different from the transformation sequences of Bi2Te3 and Sb2Te3. The stabilities of five structures of Bi2Te3 were studied by density functional theory calculations. Furthermore, an unusual irreversible relaxation process was observed. We attempted to make clear the unusual structural behavior of Bi2Se3 occurring in the compression process and the relaxation process. |
