Special Issue "Novel Thermoelectric Materials and Their Applications"
Deadline for manuscript submissions: 30 September 2020.
Interests: thermoelectric materials, thermoelectric module, ceramic nanoparticles, carbon nanotube, graphene, composite materials
Increasingly, energy and environmental research is responding to demands to address global issues surrounding environmental variation and the reduction of greenhouse gases. These issues require sustainable energy methods that can effectively recover energy waste. Thermoelectricity is considered a valuable technology of renewable energy sources due to its capacity for directly converting wasted thermal energy into useful electric energy.
Novel thermoelectric materials with cost-effective, non-toxic , high-performance properties need to be developed further, despite a possible slowing in the expansion of the thermodynamic field as a whole, in order to ensure the advancement of a flexible, reliable, high performance themoelectric module.
Hence, this Special Issue will address recent innovative work in the field of thermoelectric materials, as well as their integration into thermoelectric modules, targeted for various temperature ranges of wasted thermal energy. Potential topics include, but are not limited to:
- Bulk inorganic thermoelectric materials
- Organic or organic/inorganic hybrid thermoelectric materials
- Advances in synthesis and processing of thermoelectric materials
- Thermoelectric modules with rigid/flexible substrates
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, short communications, and reviews are all welcome.

BiSe exhibits greatly reduced lattice thermal conductivity in comparison with that of Bi2Se3, owning to the successful separation of the Bi2Se3 blocks by the metallic Bi-double-layers in its single crystal structure. However, as the increase of temperature, the thermal conductivity of BiSe increases significantly because the strong bipolar diffusion effect which is mainly caused by its small band gap that increases the intrinsic excitation. In this work, we successfully synthesize a new phase n-type Bi8Se9, and investigate the anisotropic intrinsic thermoelectric properties on the SPS samples for the first time. we reveal that in comparison with BiSe, the new compound Bi8Se9 not only has the metallic Bi-double-layers which reduces the lattice thermal conductivity, but also has a lower Bi concentration which results in a wider band gap（0.14 eV, larger than the 0.08 eV of BiSe, both values are estimated according to Eg = 2eSmaxT. Consequently, the bipolar diffusion effect in Bi8Se9 is significantly reduced. As observed, Bi8Se9 shows a bipolar thermal conductivity of 0.14 Wm-1K-1 at 673 K, much smaller than that of BiSe (0.37 Wm-1K-1 at 670 K). Finally, Bi8Se9 realizes a balance between the resistance and the Seebeck coefficient and a smaller thermal conductivity, and therefore achieves a ZT of 0.40 at 673 K.
