Abstract
A phase change material switch device is provided. The phase change material switch device includes a phase change material, a first electrode electrically coupled to the phase change material, and at least one heater thermally coupled to the phase change material. An equalization device is configured to provide an impedance coupling between the first electrode and the phase change material. The impedance coupling varies over the phase change material.
Claims13
A phase change material switch device, comprising:
- a phase change material;
- a first electrode electrically coupled to the phase change material;
- at least one heater thermally coupled to the phase change material;
- and
- an equalization device providing an impedance coupling between the first electrode and the phase change material,
- wherein the impedance coupling varies over the phase change material,
- wherein the varying impedance coupling provided by the equalization device at least partially compensates a varying electrical field over a length of the phase change material when the phase change material switch device is in a switched off state and a voltage is applied to the first electrode.
