Special Issue Information
Dear Colleagues,
Dielectric spectroscopy is a very comprehensive experimental technique that is widely used in the field of soft matter. It is an excellent technique for both basic and advanced investigations. Dielectric spectroscopy plays a significant role in the research of materials for display technologies because the switching phenomenon in a liquid crystal medium is controlled by the electric field.
By using dielectric spectroscopy, we can characterize phase and phase transitions and study the dynamics of molecular relaxations. Furthermore, we can measure dielectric and conductivity properties. The parameters obtained from dielectric spectroscopy allow us to determine other useful parameters like viscosity and elastic constants. Studies are carried out in liquid crystal cells of very different thicknesses, from micrometers to sub-millimeters, using ITO (indium tin oxide) or gold electrodes. Dielectric measurements can be performed in various conditions. We can study the effect of low (–100°C) and high temperature (+200°C) on electric response. Moreover, the effect of the bias field, different oscillation level, pressure, and various confinements can be investigated.
We invite researchers, experimentalists, and theoreticians to contribute to this Special Issue. Our goal is to combine works describing various aspects of impedance spectroscopy in material research, especially in the case of liquid crystals. We encourage the submission of original research papers and reviews.
The potential topics of the Special Issue include, but are not limited to:
- Theory of relaxation;
- Technical aspects of dielectric measurements;
- Progress and development of methods and instrumentation;
- Electric properties of newly synthesized liquid crystal materials;
- Dielectric characterization of liquid crystals doped with particles;
- Dielectric study of ionic liquid crystals;
- Relationship between the molecular structure and the electrical properties of the medium.

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.
