Ferroelectrics Materials for Microwave Devices

Dear Colleagues,

Due to their non-linear and anisotropic characteristics, polar ferroelectric materials have found many applications where integrated functionalities are required. More recently, they have attracted particular interest as electrically tunable filters, capacitors, oscillators, resonators, or phase shifters for the development of mobile telecommunication devices that need reconfiguration at microwave frequencies.

For application in microwave devices, thin ferroelectric films have been grown on various substrates using methods such as hydrothermal, sol–gel synthesis, sputtering, plasma CVD, MOCVD, PLD, etc.

Materials have been synthesized and studied at a fundamental level through modeling, fabrications, and experiments to obtain relevant compositions or phases and optimum dielectric properties.

We invite researchers to submit original papers that discuss the development of ferroelectric materials, including thin-film, nanostructured, and multilayered forms that are or can be included in microwave devices.

This Special Issue focuses on ferroelectric materials for microwave devices. The possible topics include but are not limited to the following:

• Growth of ferroelectric thin films or nanostructures, including the modeling of crystal growth or reaction mechanisms;
• Property characterization (dielectric, ferroelectric, piezoelectric, etc.) and its relationships to external conditions, such as electric field, stress, temperature, etc.
• Advances in microwave device development (conception, simulation, material integration) based on ferroelectric materials using thin films or nanostructures;
• Microstructure analysis and correlation of the observed properties and their modeling.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
