Special Issue Information
Dear Colleagues,
Phototransducers convert light into electrical signals, and are widely used for various applications including biomedical imaging, optical communications, military (e.g., night vision and security), remote and environmental sensing, etc. Two-dimensional materials such as graphene and transition metal dichalcogenide monolayers (TMDs) have emerged as optical functional materials, which are used as photosensitive materials to develop photodetectors. Especially, graphene has been a center of research due to its extraordinary material properties including broadband light absorption, high mobility, electrostatic tunability, transparency, as well as mechanical strength and flexibility. 2D materials including graphene and various TMDs (e.g., MoS2) allow for wafer-scale production, low cost, and large-scale integration. 2D materials and their hybrid systems (e.g., heterostructures of bilayered 2D materials) offer broadband and ultrafast response from ultraviolet, visible, infrared, and terahertz frequency ranges. Moreover, phototransducers based on 2D hybrid systems combined with other material platforms such as plasmonic nanoparticles and structures, perovskites, quantum dots, and other nanomaterials enable ultrasensitive light detection with broadband capability. This Special Issue will focus on the current state-of-the-art research and applications of photodetectors based on graphene and graphene-related materials (e.g., reduced graphene oxides) as well as hybrid systems realized by the combination of different 2D materials or of 2D materials and other materials including plasmonic nanoparticles and structures, perovskites, quantum dots, organic materials, and other nanomaterials.

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. Sensors 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 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.
