Special Issue Information
Dear Colleagues,
High-entropy alloys (HEAs) are alloys with five or more principal metallic elements, resulting in a large entropic contribution to free energy at high temperatures that stabilizes a single phase solid solution over potentially competing intermetallic compounds. Since their introduction in 2004, they have become a highly active area of both experimental and theoretical research due to the desirable functional and mechanical properties that HEAs may possess. More recently, the field of high-entropy materials has broadened to include different groups of nonmetallic elements. For example, “High-entropy oxides” (HEOs), referring to multicationic oxide systems, exhibit intriguing magnetic properties. In some cases, such HEO materials display extraordinary room temperature superior ionic conductivity that promises significant application in solid-state batteries. On the other hand, studying disordered semiconductors from the perspective of HEAs allows us fundamental insight into the structure–property relationships of these semiconductors. These high-entropy semiconductors serve as promising thermoelectric materials with the capability of generating electricity from temperature gradients.
In this Special Issue, we are interested in articles that explore the functional properties of high-entropy materials. Topics of interest will include, but need not be limited to:
- Computational investigations of high-entropy alloys, including high-entropy oxides, semiconductors, and superconductors, employing a variety of techniques such as ab initio methods and machine learning;
- The synthesis and characterization of the functional high-entropy alloys;
- High-entropy alloys in electronics and energy applications.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.
