压电驱动金刚石对顶砧加压装置的研制和应用

Development and application of piezoelectric driving diamond anvil cell device

  • 摘要: 金刚石对顶砧加压装置广泛用于物理、化学、材料等许多科学领域。自Bridgman发明金属对顶砧及随后发展金刚石对顶砧以来,对顶砧装置设计和加压技术得到不断发展。文章介绍采用压电驱动金刚石对顶砧来产生高压,实现低温20 K下原位连续加压,连续加压范围约2—4 GPa。该加压装置具有体积小、操作方便,可装在小型低温恒温器中使用等优点。

     

    Abstract: Diamond anvil cell (DAC) experimental technique is widely employed in the fields of physics, chemistry and materials for scientific research. Since Bridgman carried out metal anvil device and later development of DAC technique, novel design of DAC and applied pressure technique have been developed. This paper introduces the piezoelectric driving DAC device for achieving high pressure at low temperature of 20 K by in situ continuous tuning pressure. A tuning range is about 2—4 GPa. The DAC device can be easily embedded in a cryostat due to its small size and convenient operation.
