Dear Colleagues,

This Special Issue is dedicated to highlighting significant findings in the field of materials based on two-dimensional/layered systems, their hybrid structures, and composite materials. Graphene, together with a variety of newly developed 2D inorganic systems, has attracted a remarkable amount of attention due to its unprecedented properties/superior performance, encouraging its application in many fields. These two-dimensional systems are known for the fact that they are ultrathin, and hence, tend to be flexible, while also presenting nearly intrinsic and distinctive characteristics, including electronic, magnetic, optical, thermal conductivity, and superconducting properties. Furthermore, the combination of different structures and synergetic effects may open new and unprecedented perspectives, making these ideally assembled systems multifunctional and advanced materials. On this matter, significant examples come from the stacking together of 2D crystals, which can perfectly tune materials to the wavelengths of solar light. On the other hand, the ultralow sliding friction resulting from the contact between two crystalline materials or a crystalline material with a more disordered system makes superlubricity possible, which implies a reduction by orders of magnitude in friction compared to that measured for their 3D counterparts.

This Special Issue is primarily addressing two-dimensional (nano)structures and layered materials, from their syntheses/characterizations to their applications. Fundamental findings and theoretical studies contributing to the understanding of their basic principles are also welcomed.

The topics of interest include, but are not limited to, the preparation, properties, and applications of materials containing:

• Few-layered materials;
• Graphene and graphene-like systems (i.e., graphene oxide);
• Transition metal dichalcogenides, carbides, nitrides, and carbonitrides;
• Silicene, germanene, stanene, and phosphorene;
• van der Waals heterostructures, and all-inorganic and organic–inorganic hybrids;
• 2D organic framework systems and 2D polymers.

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. Materials 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 2600 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.
