Development of Basic Technologies for the DAC, Study of Structural Phase Transitions of the Elements, and Determination of Equation of States

Abstract

  Development of DAC and related basic technologies are described, including a high-pressure gas-loading apparatus. Pressure-induced phase transitions and structural change of the elements under high pressure are reviewed, focusing on the molecular dissociation of iodine and electronic topological transition in zinc. Importance of hydrostaticity for the determination of accurate equation of states is discussed.
