Diamond-anvil cell
The diamond anvil cell (DAC) technique takes the advantage of the unique properties of diamonds: highest hardness, transparent in a wide rage of electromagnetic spectrum. In a diamond anvil cell, a sample is pressurized by squeezing between two gem-quality diamonds. The sample is held within a small hole within a pre-indented thin steel/rhenium sheet with DAC. Extreme pressures (~400 GPa) can be readily achieved by using the diamond anvil cell.
Types and applications of DACs:
Mao-type symmetric cell: Angle-dispersive diffraction & double-sided laser heating |
Be-Cu cell: Electrical Transport measurement |
Cross-cell: Imaging/Inelastic scattering/radial diffraction |
Mao-type panoramic cell: Radial diffraction |
