Special Issue Information
Dear Colleagues,
Piezoelectrics are an important class of function materials that convert mechanical energy into electrical energy, and vice versa. Ferroelectrics are a special class of piezoelectrics with switchable polarization. Ferro-/piezoelectric ceramics and thin films hold key importance both in existing and new technological applications in energy storage, energy harvesting, sensors, actuators, electromechanical transducers, and micro-and nano-electromechanical systems (MEMS/NEMS), which are the building blocks of future-generation smart electronics, robotics, and the Internet of Things (IoT). With increasing concerns about the environmental and health problems in traditional lead-based ferro-/piezoelectric materials (such as lead zirconate titanate, PZT), it is imperative to develop environmentally friendly “lead-free ferro-/piezoelectric” alternatives with a similar performance. However, there are still obstacles to overcome in order to realize this objective. Therefore, this Special Issue aims to encourage efforts towards this research direction, including the latest progress in the fabrication process, the high performance, the fundamental mechanisms, the novel structural strategies, and the relationship between the structures and macroscopic properties of lead-free ferro-/piezoelectric ceramics and thin films. Research on state-of-the-art piezo-/ferroelectrics devices, namely, nanogenerators, memorizers, sensors, and transducers, is also encouraged. These materials include both inorganic (e.g., perovskite and bismuth layer-structured ferro-/piezoelectric ceramics and ZnO nanostructures) and organic (e.g., polyvinylidene difluoride (PVDF) and its copolymers and their composites, and biopolymers) lead-free ferro-/piezoelectric materials.

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. Crystals is an international peer-reviewed open access monthly 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.
