Abstract
Nanophononic metamaterials and methods for reducing thermal conductivity in at least partially crystalline base material are provided, such as for thermoelectric energy conversion. In one implementation, a method for reducing thermal conductivity through an at least partially crystalline base material is provided. In another implementation, a nanophononic metamaterial structure is provided. The nanophononic metamaterial structure in this implementation includes: an at least partially crystalline base material configured to allow a plurality of phonons to move to provide thermal conduction through the base material; and at least one nanoscale locally resonant oscillator coupled to the at least partially crystalline base material. The at least one nanoscale locally resonant oscillator is configured to generate at least one vibration mode to interact with the plurality of phonons moving within the base material and slowing group velocities of at least a portion of the interacting phonons and reduce thermal conductivity through the base material.
