Special Issue Information
Dear Colleagues,
Exactly 200 years ago, in 1821, Thomas J. Seebeck discovered the Seebeck effect, which opened a new door to generating electricity by scavenging waste heat, providing a promising carbon-neutral solution to the energy and environmental crisis. With the development of rigorous theory, sophisticated material synthesis techniques, and advanced characterization methods, in the past two centuries, and especially in the last three decades, thermoelectric materials have witnessed prominent improvement. Many new compounds have been discovered, motivated by the novel concept of “phonon glass electron crystal” and unconventional chemical bonding mechanisms. The thermoelectric figure-of-merit, i.e., zT, of iconic materials such as Bi2Te3, PbTe, and SiGe has also been greatly improved by introducing hierarchical microstructures, including dislocations, grain boundaries, and nanoprecipitates. In addition, energy band engineering, e.g., the band convergence, the band distortion, and the band anisotropy, has led to the optimization of power factors in a variety of materials systems. Aiming at the practical application of thermoelectric technology, more research has been undertaken in the design and fabrication of thermoelectric devices in recent years, but many scientific and engineering problems still need to be solved. We think it is high time to collect some high-quality research work or reviews to highlight the cutting-edge development of thermoelectric materials and to discuss the future applications of thermoelectric technology.
In this Special Issue, we welcome all kinds of research on thermoelectrics, including, but not limited to, the discovery of new thermoelectric materials by high-throughput screening, the optimization of thermoelectric properties by energy band and defects engineering, the advanced characterization of microstructures in thermoelectrics, and the design and fabrication of thermoelectric devices.

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 submissions that pass pre-check are 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 2600 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.
