  • SWITCH BASED ON PHASE-CHANGE MATERIAL
    Publication number: 20240023465
    Abstract: The present description concerns a switch based on a phase-change material comprising: a region of the phase-change material; a heating element electrically insulated from the region of the phase-change material; and one or a plurality of pillars extending in the region of the phase-change material, the pillar(s) being made of a material having a thermal conductivity greater than that of the phase-change material.
