Recent Advances in Two-Dimensional Semiconductor Materials and Optoelectronic Devices

Dear Colleagues,

Research on two-dimensional (2D) materials has been explosively increasing in the last eighteen years in varying subjects, including condensed matter physics, chemistry, materials science, life science, electronics, and photonics, since the mechanical exfoliation of graphene in 2004. From the rise of graphene, 2D materials have now become a large group with numerous members and diverse categories. The unique crystal and electronic structural features, excellent physical and chemical properties, and novel quantum effects of advanced 2D materials make them one of the most promising candidates for a wide range of potential applications in the information and energy fields.

In particular, researchers have made major progress and breakthroughs in the field of 2D materials in recent years, not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing industrialization and commercialization forward.

In this Special Issue, we invite scholars from around the world to present their latest research on advanced 2D materials and devices. The topics in this Special Issue may cover, but are not limited to, the following: (1) controllable synthesis and preparation methods, including the mechanical exfoliation, liquid exfoliation, physical deposition, epitaxial growth, chemical synthesis, and phase engineering of 2D materials; (2) microscopy, spectroscopy, and the manipulation of advanced properties and quantum effects, including the mechanical, thermal, optical, electrical, magnetic, ferroelectric, superconducting, and chirality properties and correlated electronic states of 2D materials along with newly emerging moire heterostructures and superlattices; (3) promising applications of 2D materials and devices in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc.; (4) theoretical calculations, simulations, designs, and mechanisms of 2D materials and devices.

These efforts to explore the properties of two-dimensional materials and their potential applications may provide the theoretical basis and technical guidance for realizing low-cost, large-scale, high-performance information and intelligent device applications. We welcome submissions of related work from various fields to promote collaborative research in this rapidly developing field.

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.
