Notes:
The temperature gradients in the laser-heated diamond anvil cell can be modeled through the solution of the steady-state heat equation. For a given laser, the width of the hotspot is dependent on the thickness and thermal conductivity of the sample and of any thermal-insulation layers between the sample and the diamonds. For a given sample, insulation and peak temperature, thicker samples will have broader hotspots than thinner ones. Therefore, increasing the pressure on a sample will thin the gasket, sample and insulation, producing a narrower hotspot and increasing temperature gradients. © 2001 American Institute of Physics.
