Electrical transport experiments play a key role in the study of many interesting high pressure phenomena, including pressure-induced superconductivity, insulator-to-metal transitions, and quantum critical behaviour. High-pressure electrical transport experiments also play an important function in geophysics and Earth’s interior studies.
However, such measurements in a diamond anvil cell (DAC) have been very challenging with several different ‘recipes’ being adopted with various degrees of success. Almax easyLab offers diamond anvils with deposited gold patterns for electrical transport measurements in a DAC. Our patterned diamond anvils significantly facilitate such experiments.
Almax easyLab’s patterned anvils together with the Diacell® ChicagoDAC or Diacell®CryoDAC-PPMS enable seamless transport measurements at extreme conditions.
The Almax easyLab patterned anvils are ideal for transport and other electrical measurements in a diamond anvil cell. As the 4 metal probes are not embedded, these patterned anvils still require gasket insulation and can be used at moderate high pressure only (up to 10 – 20 GPa). Electrical contact between the sample and the conductive patterns on the diamond anvil can be made in a variety of ways, such as with silver epoxy, silver paint and even soft solder.
There are two configurations readily available:
C = 0.40 mm approx., Cb = 0.45 mm approx. at 8º with probe inter-distance of 100 µm approx.
C = 0.80 mm approx., Cb = 0.85 mm approx. at 8º with probe inter-distance of 200 µm approx.
