1-Silicon phononic crystals for thermoelectric applications
- Context :
- Not only is most of the energy in electronic devices lost, heating the chip, but this is a much more general phenomenon as more than 60% of man-produced energy is lost as heat.
- Objectives :
- We aim at retransforming this wasted heat back into electricity, but also collecting it from the environment in order to design energy autonomous systems including wireless transmission. The first goal is to be able to control the heat flow in silicon structures. This will also open prospects in heat management at the nanoscale in electronic chips.
- Methods :
- We try to create a structure which will block the heat carriers, namely phonons, while keeping the electrical conductivity identical by creating periodic nanostructures, called phononic crystals, in thin membranes. To ensure an optimal compatibility, we investigate the use of silicon, which also allows finer designs as its fabrication process is quite well known.
- By taking advantage of boundary scattering, size effects and coherent phonon transport, the thermal conductivity can be adjusted, hopefully down to the level of amorphous silicon oxide. The structures need to be carefully designed to efficiently suppress phonons carrying heat.
- The first objective is to demonstrate the coherent phononic effect by measuring the phononic crystals thermal conductivity at low temperatures.
- Results :
- Three types of structures haves been fabricated: nanowires, 1D fishbone periodic structures and 2D phononic crystals. For similar characteristic sizes, the thermal conductivities are reduced in this same order and further reduction due to possible coherent transport has been observed in 2D phononic crystals.
