Abstract
Sensor interconnects and supports and methods of making them utilize phonon disruptors for increased thermal resistance while maintaining acceptable electrical signal quality in materials. Phonon disruptors include, but are not limited to, structural features such as interfaces, grain boundaries, and point scattering sites, for example, that are designed to scatter heat carriers while allowing electrons to pass through the material. Some embodiments herein involve designing selected stacks of alternating or sequential material pairs within sensor interconnects.
