Special Issue Information
Dear Colleagues,
A topological insulator (3D) is a material as an insulator in its interior with conducting states at the surface, resulting in electrons only being able to move along the surface of the material. Meanwhile the conducting surface states, which are protected by symmetry with a non-trivial topological order, exhibit spin-momentum locking behavior suitable for spintronics. The 2D counterpart of the topological insulator, i.e., the quantum spin Hall material, also exhibits symmetry-protected non-trivial topological order spin-momentum locking states at the edges of a 2D thin film. Besides the 3D and 2D topological insulators, researchers have also discovered many topologically-protected materials such as magnetic topological insulators, topological Dirac, Weyl, and nodal-line semimetals. Furthermore, several topological superconductors, which can host Majorana Fermions for fault-tolerant quantum computers, have also been proposed recently. As such, this Special Issue is dedicated to discovering new types of 2D or 3D topological matters, to achieve a better understanding of their intriguing properties, and to develop potential applications based on topological 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. 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.
