Advances in Growth, Coating, and Integration of 2D Materials

Dear Colleagues,

Two-dimensional materials, such as Graphene, Transition Metal Dichalcogenides (TMDs), and h-BN, have attracted increasing interest because of their peculiar optical, electronic, and electrical features, involving potential applications in a wide range of fields such as electronics, optoelectronics, and sensing.

The development of scalable deposition methods for the wafer-scale integration of 2D materials represents a key requirement in exploiting such exceptional properties. Currently, Chemical Vapor Deposition (CVD) represents one of the most suitable and employed bottom-up approaches to grow 2D materials. Current research is focused on understanding the mechanisms which govern the nucleation and coalescence of various 2D materials, with the aim of achieving higher control in terms of crystalline quality and thickness uniformity on a large area.

This Special Issue aims to collect significant contributions on advances about the following topics:

1. Growth, coatings, and the integration of 2D materials on appropriate substrates (metallic, semiconductive, or insulating) by bottom-up approaches such as CVD, molecular organic CVD (MOCVD), atomic layer deposition (ALD), two-step CVD (also known as sulfurization/selenization of ultrathin films), Pulsed Laser Deposition (PLD), Molecular-Beam Epitaxy (MBE), and other alternative scalable methods.
2. Spin-coating with 2D materials produced by top-down methods such as exfoliation and liquid exfoliation will be considered for this Special Issue.
3. Optimization of the transferring methods by polymer-assisted coating with 2D materials for integration on alternative substrates.
4. Investigation of the surface properties of coated/deposited 2D materials on the corresponding substrate.
5. The understanding and development of advanced solutions to increase the yield of the adsorption and adhesion of 2D material precursors on the surface, with control of the development of thin films or isolated domains.
6. Deeper insight into the 2D material/substrate interface, which can functionalize the 2D materials in terms of strain, doping, and electrical/optical features.
7. Understanding the effects induced on the grown/coated 2D materials after high-temperature exposure, which can involve stress and degradation.
8. Advanced multiscale characterization methods to probe the uniformity, crystalline quality, and electrical/optical properties of 2D layers grown using the different approaches will be in the scope of the Special Issue, too.
9. High-impact applications of 2D materials in fields like electronics, optoelectronics, sensing, catalysis, and energy harvesting, as well as biomedical applications, are

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. Coatings 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 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.
