Special Issue Information
Dear Colleagues,
The area of gas sensors application is rapidly expanding. This leads both to the expansion of the range of target gases and a greater variety of their detection conditions: temperature, humidity, interfering compounds. Semiconductor materials are of exceptional interest for the development of gas sensors that can be integrated into miniature devices and convert information into electrical signals with high sensitivity and speed.
Wide-gap metal oxides SnO2, ZnO, WO3, In2O3 are most widely used to create gas sensors. However, despite their high sensitivity and easy manufacturing, these materials have limitations in selectivity, especially when analyzing gas mixtures in humid conditions. Overcoming these limitations is the main focus of research in the field of sensor materials science. A significant amount of work falls on semiconductor structures consisting of different compounds. Studies consider nanocomposites, organic–inorganic hybrid materials, and n-n and n-p heterostructures. At present, the full potential of the new material is difficult to imagine, as information is still being accumulated. This Special Issue of MDPI Sensors can become a scientific platform for discussing the characteristics of sensors based on complex semiconductor materials.
Thus, you are invited to submit contributions devoted to the synthesis and characterization of semiconductor structures of different type and composition and their characterization in relation to specific gas sensor properties:
- n-n and n-p semiconductor heterostructures
- metal oxide-based nanocomposites
- Organic–inorganic hybrid semiconductor materials
- Complex oxide (spinels, perovskites, etc.) semiconductor materials

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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
