  Título: Quantum Materials for Thermoelectric Devices

  Resumo:
  The Research and Development community remains highly focused and motivated towards shifting the current worldwide energy matrix towards clean and renewable energy. Here we present an overview of recent progress in the area of Thermoelectrics, one of the promising contributors to this goal but which has so far remained limited to “niche” applications. We begin by describing the basics of thermoelectric (TE) devices in their two most common realizations – thermoelectric generators (TEG) and thermoelectric coolers (TEC), followed by the recent advances in the search for novel high-performance TE materials, mostly among strongly correlated electron systems, complex cage compounds and topological materials. Contemporary approaches towards improving the efficiency of heat–electricity conversion (energy harvesting and heat pumping) are discussed through the understanding of various emergent physical mechanisms. The strategies for decoupling the individual TE parameters of relevance to device performance, as well as the simultaneous enhancement of the TE power factor and the suppression of heat conduction, are described and the perspectives of achieving breakthroughs that may allow TE devices to become a mainstream contributor to energy applications are discussed.
