Ensuring a sustainable energy supply is one of the grand challenges for science and technology in the 21st century. There is an urgent need for improved ways of generating power, without heavy reliance on fossil fuels. Thermoelectric devices, which exploit the Seebeck effect to provide direct conversion of thermal energy into electrical energy, offer considerable attractions for a more efficient use of existing energy resources. In particular, thermoelectric power generation enables useful electrical power to be extracted from waste heat. However, the performance, cost and availability of thermoelectric materials are significant barriers to the broad implementation of thermoelectric technology. Commercial thermoelectric devices are still largely based on bismuth telluride alloys, and their thermoelectric figure of merit, ZT ≈ 1, combined with the scarcity of tellurium, limit these devices to niche applications.
For these reasons, research in thermoelectric materials is very active worldwide, with the field rapidly advancing into entirely new classes of materials. This encompasses not only a wide range of inorganic materials, but also organic molecules and polymers. This Special Issue will focus on recent advances in thermoelectric materials. Potential topics include, but are not limited to:
- New thermoelectric materials, as well as optimisation by doping of existing materials
- Bulk inorganic thermoelectric materials
- Organic and polymer thermoelectric materials
- Nanoscale thermoelectric materials, including composites
- Advances in thermoelectric materials synthesis and processing
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract: Since 1997, with the discovery of large thermoelectric (TE) properties in NaxCoO2 great efforts have been carried out to explore new CoO families with high TE performances. Following this intense research work, some layered cobaltites, such as Ca3Co4O9 and Bi2AE2Co2Ox (AE = alkaline earth) were also found to exhibit promising thermoelectric properties. As layered CoO oxides are materials with strong crystallographic, electrical and thermal anisotropy, a proper alignment of the grains is necessary to attain interesting TE properties in bulk samples. On the other hand, in order to be adequate for practical applications these materials should maintain their high TE properties, as well as their mechanical ones, at high temperatures for long time.
Taking into account these previously discussed effects, Bi2Ba2Co2Ox samples have been directionally grown from the melt using the laser floating zone (LFZ) technique. In order to study the samples behaviour at working temperatures, annealed samples have been maintained at 700ºC under air for different time lengths (0, 12, 24, 48, 96, 192, 384, 768 and 1536 hours). The evolution of microstructure, TE and mechanical properties has been studied as a function of the thermal treatment length.
