Special Issue Information
Dear Colleagues,
For many years, the principal strategy to improve the sensitivity of solid-state sensors has been to increase the surface area in contact with the environment or to fabricate thinner sensing films. Since sensing primarily occurs at the film’s surface, while conductivity is a bulk property, thinner films provide an increase in the surface-to-volume ratio which improves the sensitivity. While graphene has received the most attention in the last few decades, research has struggled to provide a working graphene-based field-effect transistor (FET) due to its lack of a bandgap. In the meantime, a host of other potential two-dimensional (2D) materials have risen in prominence, such as transition metal dichalcogenides (TMD).
TMDs are 2D semiconductors composed of a layer of transition metal atoms sandwiched between monoatomic layers of chalcogens (e.g., MoS2, WS2, MoSe2, WSe2, MoTe2). These materials are attractive for sensing applications due to their layered structures which increase the surface effects, the presence of an adjustable bandgap, sufficient conductivity, strong photoluminescence, a large exciton binding energy, and low cytotoxicity.
This Special Issue invites research papers and reviews on all topics related to the utilization of 2D TMDs for sensing applications including, but not limited to, the following:
- Room-temperature gas sensors;
- Photodetectors;
- Thermal detectors;
- High-sensitivity pressure sensors;
- Biosensors;
- Acoustic sensors;
- Flexible nanosensors;
- Piezoelectronic devices;
- Effects of TMD layer growth and synthesis on sensor behavior.

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. Materials 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.
