Diamond anvil cell with boron-doped diamond heater for high-pressure synthesis and in-situ transport measurements

Abstract

Temperature and pressure are essential parameters in the synthesis, evaluation, and application of functional materials. This study proposes the addition of a heating function to a high-pressure diamond anvil cell (DAC) with in-situ measurement probes. The proposed DAC allows for simultaneous control of temperature and pressure within the sample space and can be used to synthesize functional materials under extreme conditions. The various components, namely the heater, thermometer, and measurement probes, were fabricated with a boron-doped diamond epitaxial film and could be used repeatedly. The developed DAC was used to successfully conduct the high-pressure annealing of La(O,F)BiS${}_2$ single crystal and the high-pressure synthesis of EuFBiS${}_2$ superconductors. The proposed technique shows promise for further exploration of superconductors to broaden the research field.
