Special Issue Information
Dear Colleagues,
Lead (Pb)-free polar oxides, as environmentally sustainable alternatives to their Pb-based counterparts, have reached a certain level of maturity, since research in this area started about a decade and a half ago. Here, the broader term ‘polar oxide’ is meant to include materials with different polarization behavior in response to applied electric fields, such as ferroelectrics, antiferroelectrics and relaxors. They are indispensable in different technological fields including high-power capacitors for power conversion, sensors and actuators for smart applications, energy harvesting from waste heat or ambient vibrations, healthcare devices and space exploration.
While several promising Pb-free ferroelectrics have come forth in recent years, their broader industry wide adoption has not kept pace with expectations. We identify three principal issues for this scenario: (a) easy and reliable synthesis of complex compositions, (b) characterization of atomic scale and mesoscale structural complexities, and (c) modelling of structure-property correlations under different operating conditions.
This Special Issue aims to convene recent scientific breakthroughs to address these issues using approaches including, but not limited to, new materials synthesis and processing methods, electron/X-ray/neutron based structural characterization tools, and modelling techniques including first-principle computations or data-driven modelling.

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.
