Special Issue Information

Dear Colleagues,

This Special Issue on “Compounds with Polar Metallic Bonding” is intended to open an exchange between chemical, physical and material-oriented disciplines committed to intermetallic systems with strongly correlated electrons. The term “polar metal” is ubiquitous here, and can describe numerous different effects. Polarity can indicate the interplay of conduction electrons with magnetic dipoles in the lattice. It can also describe the presence of electric dipole moments within a ferroelectric metal. Additionally, the term is used when referring to an intermetallic phase crystallising in a polar space group, or when electronegativity differences between the constituent elements of an intermetallic phase induce Coulombic interactions within an overall metallic matrix.

In all these cases, polarity induces new, interesting property combinations in metallic systems. To understand the mechanisms in this field, it is necessary to understand interplay between localised moments, as electric or magnetic dipoles, as well as Coulombic monopoles with the delocalized conduction electrons. For the establishment of structure–property relations for compounds with polar metallic bonding it is indispensable to present reliable models of their electronic structures. In order to understand the electronic consequences of polarity on the basis of quantum-mechanical calculations, it is necessary to have detailed crystal structure models at hand. Additionally, prior to crystal structure elucidation there is, of course, chemical synthesis.

We would like to combine reports on all related topics in this special issue. Some specifically interesting topics that may be included are listed below as keywords. These should only be considered as examples—any advanced topic in the field of polar metallic bonding is welcome.

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 papers will be 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 1200 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.
