Special Issue Information

Dear Colleagues,

The design of thermoelectric materials with improved efficiency in order to convert heat into electricity and vice versa has attracted a great deal of theoretical and experimental research interest in the last two decades. Fundamentally understanding the mechanisms that govern heat and carrier transport is the key to producing high-performance thermoelectric devices with cooling and power generation applications.

The efficiency of energy conversion is measured by the dimensionless figure of merit ZT, which is the product of the square of thermopower,  electrical conductivity and temperature divided by the thermal conductivity.  Good thermoelectric materials are those with ZT > 3 at room temperature. In principle, ZT can be increased by increasing the thermopower and electrical conductivity and by reducing the thermal conductivity. However, the interrelations between the above transport coefficients make their independent variation a challenging task. 

The aim of this Special Issue is to present new developments in the optimization of ZT by tuning the electron or/and phonon transport properties of both inorganic and organic semiconductors. Theoretical and experimental studies on materials of reduced dimensionality (2D, 1D, and 0D) are particularly encouraged.  Emphasis is given to band-gap engineering, the control of electron and phonon scattering mechanisms, and electron–phonon coupling (i.e., phonon-drag effect). This Special Issue will include both full research and review papers.

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.
