Special Issue Information
Dear Colleagues,
2D materials have turned out to be a very exciting playground for the next generation of optoelectronic devices. This is fostered by their unique characteristics: They are mechanically robust, but flexible, and as van der Waals materials they can be integrated into a great variety of architectures without lattice constraints. They exhibit strong light-matter interaction; however they are fairly transparent due to their atomic-scale thickness. By taking benefit from their valley degree of freedom innovative devices with e.g. controlled helicity of emitted light can be developed. The large surface can be used to add enhanced functionalities to light sensors like sensitivity to the surrounding or gas detection. Many more promising concepts are emerging daily, stimulating a highly inventive research field. With the rise of industrial methods to produce 2D materials and heterostructures on large scale, recent works presented important steps on the way from lab to fab, but many challenges still have to be met, e.g. increasing quantum efficiencies or avoiding carrier losses during injection/extraction. Theoretical understanding of transport and recombination mechanisms and the role of defects is an indispensable requirement to develop new and innovative devices.
The purpose of the present Special Issue is to present state-of-the-art research on optoelectronic devices based on 2D materials. It shall collect exciting concepts, theoretical background, relevant material synthesis and characterization, and of course novel devices by leading groups in the research community.

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. Nanomaterials 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 2900 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.
