Semiconductor Quantum Dot Superlattices for Thermoelectric Applications
Abstract
We have theoretically investigated the in-plane lattice thermal conductivity of a quantum dot superlattice that consists of arrays of ordered quantum dots. Our theoretical model takes into account scattering of acoustic phonons on quantum dots made out of material with a finite acoustic mismatch with the host material. Modification of phonon dispersion in the quantum dot superlattice has also been incorporated into the model. Numerical simulation has been carried out for the quantum dot superlattice made out of multiple Si layers with Ge quantum dots. Obtained results are important for suggested applications of Si/Ge quantum dot superlattices for high-temperature thermoelectric devices.
