Mathematically, a 2D crystal is unstable in free space. This does not prevent 2D materials from existing, as first demonstrated by Novoselov and Geim in 2004 with graphene. In most applications, a 2D layer is held by a solid surface on which it sticks. Fortunately, the interaction with the substrate can be weak enough to preserve the intrinsic properties of the 2D overlayer. As theory and experiment have demonstrated, these properties are remarkably different from those of usual 3D materials.
The study of 2D materials has rapidly become topical in nanosciences as more and more structures have been discovered. Elemental 2D materials include graphene, graphdiyne, silicene, phosphorene, borophene, and others. In addition, numerous compounds have been produced in the form of molecular monolayer and their properties analyzed: hexagonal BN, SnS, transition metal dichalcogenides, MXenes, etc. The electronic structures of 2D materials range from metal to semiconductor while, interestingly, a few of them demonstrate magnetic order.
Different 2D materials can be stacked in sandwich heterostructures held by van der Waals forces. Layers with different electronic properties can be assembled thereby with almost endless combinations and potential applications. Lateral heterostructures can also be imagined where two half layers are stitched together by covalent bonds.
The world of 2D materials has only been partly explored, numerous discoveries are still to come. This Special Issue offers the opportunity for actors in this area to publish their recent results in full open access.

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 2300 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.
