Graphene and Other 2D Materials: Technologies, Methods and Applications

Dear Colleagues,

Since the first demonstration of the unique properties of the thinnest possible material in nature, graphene, in 2004, it attracted enormous researchers’ interest all over the world. The reason for such a huge interest in graphene is its fascinating electronic, optical, and mechanical properties, such as the high mobility of charge-carriers, the high transparency of graphene in combination with its electrical conductivity, the possibility of the electrical control of its optical properties in the particularly interesting THz-to-FIR spectral range, strong optical non-linearities, extraordinary elastic properties, and high mechanical robustness (compared to other materials of the same thickness). These and other properties of graphene opened the door to a series of already existing and potential practical applications like power grids, photodetectors, sensors, light sources, anti-corrosion coatings, conducting paper, etc. The whole area of THz plasmonics has arisen thanks to graphene.

The graphene boom gave rise to other important consequences. First, it spurred the search of other two-dimensional materials, which has already yielded transition metal dichalcogenides, TMDs (2D semiconductors), boron nitride, h-BN (2D insulator), as well as a number of 2D magnetic materials, Xenes, etc. In particular, the TMDs support extremely robust excitons and are characterised by a strong spin-valley correlation, while optical phonons in the h-BN are hyperbolic (with different signs of the group velocity in different directions). These unusual properties promise new interesting physics and important applications. Secondly, the honeycomb crystal structure, which is characteristic of graphene and TMDs and is responsible for some of their unique properties, inspired mimicking it in other systems, such as cold atoms and photonic crystals.

This Special Issue aims to gather original research articles and review papers describing experimental and theoretical results concerning the research in the area of graphene and other 2D materials. It is open to contributions covering both fundamental research, materials properties, and applications, including 2D material-based photonic, (opto-) electronic, sensing, and mechanical devices.

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.
