Dielectric, Ferroelectric and Piezoelectric Properties of Nanomaterials

Dear Colleagues,

With the fast-paced development of ferroelectric nanomaterials, the downscaling of their electrophysical properties, including their polarization-centered ferroelectric property and polarization-derived dielectric and piezoelectric properties, has become a critical issue when considering their applications in miniaturized and integrated devices. This is primarily due to the fact that ferroelectricity is a long-range polar order, which can be undermined or even totally lost under the size reduction constraints imposed by the microelectronics industry.

The aim of this Special Issue is to explore the aforementioned electrophysical properties in ferroelectric thin films/multilayers/superlattices, nanorods/nanowires/nanotubes/nanofibers, and nanoparticles. We welcome all research works that focus on these properties in ferroelectric nanomaterials, including but not limited to the following:

• Those reporting the downscaling status quo in ferroelectric nanomaterials (how do their properties compare with the bulk ones?) and analyzing the impacting factors;
• Those that model/simulate the critical size for a scalable electrophysical property, or the property itself in a nanomaterial or a miniaturized device;
• Those that present a novel method or create a novel microstructure to address/mitigate downscaling issues, or to endow ferroelectric nanomaterials with excellent or tailor-made electrophysical properties;
• Those that design, characterize, or fabricate ferroelectric nanomaterials or prototype devices targeting the aforementioned properties or property-related applications, etc.

Lastly, antiferro-electric nanomaterials and their related properties are also within the scope of this Special Issue, as they can transform into a ferroelectric phase under the application of an external electric field.

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. Nanomaterials 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 2900 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.
