Special Issue Information
Dear Colleagues,
The advances in non-centrosymmetric crystal materials greatly promote the development of multifunctional devices, taking advantage of piezoelectric, ferroelectric, pyroelectric, non-linear optic and electro-optic effects and affect many aspects of industry fields. These crystal materials are capable of achieving the mutual conversion of different energies, including light, electricity, heat, magnetism, mechanical force and so on. Among the non-centrosymmetric crystals, the piezoelectric, ferroelectric and nonlinear optical crystal materials have attracted a lot of attention in recent decades.
Extensive studies have been implemented on designing new non-centrosymmetric crystal materials and/or optimising the opto-electric functions of crystal materials to improve the selectivity of crystal materials for device applications. Crystal growth has also been proposed to enhance the piezoelectric, ferroelectric and nonlinear optical response. Firstly, the absence of grain boundaries in single crystals enables a larger volume of the material, contributing to the electromechanical and nonlinear responses. Secondly, the chemical doping in piezoelectric, ferroelectric and nonlinear optical crystals can manipulate the microscopic polarization, thus improving the macroscopic opto-electric properties. Thirdly, the low-dimensional piezoelectric, ferroelectric and nonlinear optical crystals would be conducive to the findings of interesting electrical and optical behaviours.
This Special Issue aims at covering all the relevant aspects of piezoelectric and nonlinear optical crystal materials. Both well-established, novel, or less common compounds, and micro mechanisms in single crystals will be covered. Therefore, the Issue welcomes original research and review manuscripts on the following main aspects:
- Development and design of non-centrosymmetric crystal materials
- Piezoelectric and/or ferroelectric crystals and films
- Nonlinear optical crystals
- Piezoelectricity
- Ferroelectricity
- Domain engineering
- Crystal defects
- Opto-electric property characterization
- Theoretical study with Ab-initio, DFT, and first principle calculations on non-centrosymmetric crystal 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 2100 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.
