摘要	In this study, first-principle,calculations, in situ angle-dispersive X-ray diffraction, and in situ electrical resistance measurements were performed on arsenic telluride (As2Te3) under high pressure. Structural phase transitions and metallized phenomena were observed from the calculated and experimental results. Upon compression, alpha-As2Te3 transforms into phases alpha' and alpha '' at similar to 5.09 and similar to 13.2 GPa, respectively, with two isostructural phase transitions. From 13.2 GPa, As2Te3 starts to transform into phase gamma, with one first-order monoclinic to monoclinic crystal structural phase transition. According to the first-principle calculations and electrical resistance measurements, the structural phase transitions in the compression process induce the transformation from an insulator (phase alpha) across a semimetal (phase alpha') into a metal (phases alpha '' and gamma). The evolution of the structure and transport property upon compression on As2Te3 is helpful for understanding the properties of other A(2)B(3)-type compounds under high, pressure.
