Switch based on phase change material

The present description relates to a phase change material-based switch, comprising: a phase change material region; a heating element electrically insulated from the phase change material region; and one or more pillars extending in the phase change material region, the pillars being made of a material having a thermal conductivity greater than that of the phase change material. 本说明涉及一种基于相变材料的开关，包括：相变材料区域；加热元件，与相变材料区域电绝缘；以及一个或多个柱状件，在相变材料区域中延伸，柱状件由具有大于相变材料的导热率的导热率的材料制成。
