Thermoelectric technology is one of the most promising approaches for efficient energy harvesting. Thermoelectric energy conversion efficiency is defined by the dimensionless figure of merit ZT = σS2T/κ, where σ, S, κ, and T are the electrical conductivity, Seebeck coefficient, thermal conductivity, and absolute temperature, respectively. State-of-the-art thermoelectric materials exhibit relatively high ZT values at temperatures lower than 400°C, which is important for practical energy-harvesting applications. However, the ZT values of existing thermoelectric materials are still too low for practical applications.
Multiscale structuring has been regarded as one of the most promising approaches to enhance the ZT value of a thermoelectric material by enhancing phonon scattering with maintaining good carrier transport properties. To fabricate thermoelectric materials with a hierarchically-organized multiscale defect structure, the bottom–up preparation approach in which chemically-synthesized nanoparticles (NPs) are used as building blocks is promising. This enables us to easily create exotic structures never before possible by introducing atomic defects in NPs (including impurities) during the synthesis, controlling size and shape of the NPs, blending two or more different types of NPs for making a bulk material, and controlling mesoscale defect structures by taking advantage of the pulse electric current sintering (PECS) technique.
This Special Issue will cover all aspects of novel thermoelectric NPs, including chemical synthesis, characterization, or applications of those NPs.
It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
