Abstract

The goal of this project is to investigate the thermoelectric response in candidates Topological Crystalline Insulators (TCI) and heterostructures with the aim to bring relevant insights in the understanding of organization of charge carriers in this class of materials and to explore new routes for enhancing thermoelectric performance. To do so, we plan to carry out a systematic and comparative study on bulk and thin films SnTe (PbTe as counterpart). The growth and characterization of thin SnTe films (and heterostructures) will be done at IFUSP. The investigation of thermoelectric and thermal properties at low temperature (down to 1.5K) and under the application of magnetic field (up to 9T) will be carried out in the LQMEC laboratory at IFUSP, developing ad-hoc home-made experimental platforms.
