Special Issue Information
Dear Colleagues,
Optoelectronic applications of 2D materials have been the focus of much of the research efforts performed on these systems, since the isolation of graphene. The unique structural and physical properties of these atomically-thick layers, and their strong interaction with light, make them indisputable candidates for their integration in devices designed to generate, detect, interact with, or control light. High mobility, fast response, and high photo-responsivity are among the targeted goals, and recently reported, for devices based on graphene, transition metal dichalcogenides, or black phosphorus. In addition, the dependence of the electronic properties on the number of layers (i.e., bandgap) or the possibility to externally tune them (i.e., by doping or by external field), further increases the potential application of 2D materials in optoelectronic devices.
The possibility of stacking together different 2D materials with accurate control over the number of layers and their relative position and orientation, makes heterojunctions even more interesting than 2D materials themselves for optoelectronic applications. Within this framework, many researchers are investigating the carrier transfer behavior and quantum coupling effect in these heterojunctions, which can also present novel physical properties.
This Special Issue of Nanomaterials will cover recent advances in 2D materials and heterojunctions with applications in optoelectronics, including LEDs, lasers, photovoltaics, and photodetectors devices.

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 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.
