2D-Materials Photonics

Dear Colleagues,

Over the last two decades, two-dimensional layered materials have received tremendous research attention due to their novel properties and physical phenomena, as well as their emerging applications in nanophotonics and optoelectronics. Optical spectroscopy, such as Raman scattering and photoluminescence, has proven a unique tool to gain insight into many of the fundamental aspects of different families of 2D materials. It has enabled significant advances concerning the influence of external perturbations such as mechanical strain (uniaxial or biaxial), temperature, intentional or unintentional doping, and high hydrostatic pressure on the electronic, phonon, and mechanical properties of 2D membranes. Importantly, in many compounds, the low dimensionality reduces the dielectric screening resulting in unprecedented strong exchange and many-body interactions that give rise to uniquely intense excitonic effects, having a strong impact on their optical spectra. Moreover, in thicker 2D materials, optical spectroscopy has made a significant contribution toward the understanding of various features of interlayer coupling, including different stacking arrangements, Moiré superlattices, planar or vertical heterostructures, providing a playground for the observation of fascinating quantum phenomena.

The aim of this Special Issue is to review recent experimental and theoretical advances in the field of optical spectroscopy of 2D materials. Emphasis should be given to identifying future research directions and open questions in this emerging field of research. As Guest Editor, I cordially invite you to submit a manuscript to the “2D Materials Photonics” Special Issue.

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.
