About this Research Topic
In recent years, density functional theory and state-of-the-art experimental facilities have facilitated major advances in condensed matter physics. Thermoelectricity has regained attention in recent years for alternative sustainable sources of energy. The thermoelectric materials capable of converting heat into electrical energy and vice versa can therefore be useful for energy harvesting applications at numerous places such as power plants, factories, automotive exhausts, etc. Thermoelectric materials are also used in a variety of power generation and cooling applications. With emerging new fields of applicability, the future potential for thermoelectric materials is huge.
Thermoelectricity involves converting waste heat into electricity and creating a cooling effect by using electricity. The challenge is to search for materials having good electrical conductivity and low thermal conductivity so as to enhance the efficiency of conversion. There are many strategies to enhance the thermoelectric figure of merit of the materials to make devices. Recently, 2D materials have attracted a lot of interest due to their low thermal conductivity and high figure of merit. The creation of defects and strain engineering is leading the way to highly efficient materials for device applications.
In this Research Topic, we seek Original Research articles and Reviews in the field of thermoelectricity. Submissions should address structure stability, transport properties, device applications, exploring new materials as well as discovering new phenomena. In recent years a lot of emphasis has been laid on increasing the thermoelectric figure of merit by applying strain, doping and lowering dimensionality of the materials. This Research Topic will address a broader area of condensed matter physics including theoretical and experimental investigations of electronic structure, transport coefficients and material stability at high temperatures.
