摘要 | Using a diamond-anvil cell (DAC), we conducted in situ angle dispersive X-ray diffraction (ADXRD) up to 47.6 GPa at room temperature to evaluate the structural stability of alpha-As2Te3. A reversible structural transition was observed at between 17.4 and 36.3 GPa. The high-pressure structure is solved by a gamma-Bi2Te3-type monoclinic phase (C2/c, gamma-As2Te3). Reliable structural analyses, such as Rietveld refinement of the powder x-ray data, were provided, which show that the previously reported high-pressure beta-As2Te3 phase is not existed. It is worth mentioning that twice pressure-induced electron phase transitions were revealed in alpha-As2Te3 at about 3 and 6 GPa, which cause the striking fluctuation in thermoelectric property at that pressures.
