Advanced Optoelectronic Materials/Devices and Their Applications

Dear Colleagues,

Optoelectronic materials and devices play a pivotal role in modern technologies, enabling advances in photonics, renewable energy, displays, and sensing. With innovations in semiconductors, perovskites, 2D materials, and hybrid systems, these devices are driving breakthroughs in solar cells, LEDs, photodetectors, and next-generation imaging systems. Their applications span new energy, telecommunications, biomedical diagnostics, environmental monitoring, and the Internet of Things, highlighting their transformative potential across multiple disciplines. This Special Issue focuses on the latest research progress in optoelectronic materials and devices, including novel material design, single-crystal growth, thin-film interface optimization, device architecture engineering, and material/device stability, while also exploring fundamental operational mechanisms. The issue emphasizes current challenges and emerging opportunities in this fast-evolving field to foster breakthroughs in next-generation optoelectronic technologies. Topics of interest include, but are not limited to: novel optoelectronic materials; high-performance photodetectors, LEDs, and laser devices; perovskite and organic photovoltaics for energy conversion; flexible/wearable optoelectronics systems; device physics, stability, and scalable fabrication techniques; characterization of novel optoelectronic films and 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 250 words) can be sent to the Editorial Office for assessment.

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. Micromachines is an international peer-reviewed open access monthly 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 2100 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.
