Synopsis:
Controlling the thermal conductivity of materials is of interest in optimizing the performance of thermoelectric devices. The insertion of nanometer inclusions in a semiconductor is an effective means of achieving such control. In this work, we study the unexpected thermal properties of silicon metalattices that consist of a periodic distribution of spherical inclusions embedded into a silicon matrix.
