Novel 2D Material-Based Sensors for Optoelectronic Devices

Dear Colleagues,

Recent advances in the fabrication methods of two-dimensional (2D) materials and their corresponding ease of availability for research purposes have contributed to the conception of novel optoelectronic device structures, offering interesting opportunities for developing highly sensitive, efficient, and versatile sensors with a direct view of real-life applications. By exploiting the unique electronic, optical, and mechanical properties of atomically thin materials, a new generation of sensors has been proposed to address challenges in various applications. The most frequently used materials are graphene and its allotropes, transition metal dichalcogenides (TMDs), hexagonal boron nitride (hBN) and black phosphorus. This Special Issue explores novel configurations for optoelectronic sensor architectures interfaced with these 2D materials, including their design layout, fabrication methods and applications, with particular emphasis on photodetection for chemical and biological sensing. For the active control of light–matter interactions and the plasmonic effect enhancement and manufacturing of 2D reconfigurable metasurfaces, these unique elements permit new capabilities in manipulating light at the nanoscale and expectedly integrate into the sensing components of the future generation cyber–physical system directed to support the human-centered paradigm of Society 5.0 and Industry 5.0.

Targeting devices, as well as application systems in a unified approach, represent an innovative and interdisciplinary research area, expanding from material science, physics, photonics, automation and control systems to biochemistry, nanotechnology, and low-power electronic systems. This Special Issue supports the dissemination of recent research in this area and invites you to submit manuscripts, research papers, or reviews, welcoming multiple perspectives related to this topic.

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.
