Special Issue "Synthesis and Engineering of Optoelectronic Properties of Two-Dimensional Perovskites"

Dear Colleagues,

Two-dimensional (2D) metal halide perovskites have attracted much attention in recent years due to their promising applications, including in light-emitting diodes (LEDs), solar cells, lasers, and photodetectors. Various chemical methods at ambient conditions have been developed for the synthesis of environmentally stable 2D perovskites with intriguing optoelectronic properties, such as large exciton binding energy, a high photoluminescence quantum yield, and a tuneable bandgap. To achieve these breakthroughs related to novel properties, extreme conditions, such as a high pressure, low temperature, and strong magnetic field, have been introduced into the engineering process. This facilitates researchers in unravelling some of the fundamental photophysical properties of 2D perovskites. This Special Issue covers topics pertaining to the synthesis of novel 2D perovskites and the engineering of optoelectronic properties of 2D perovskites through the application of pressure, strain, changing temperatures, and magnetic fields, in addition to physical-based simulations and calculations of the engineering process. The goal is to achieve a diverse collection of 2D perovskites by using special chemical methods, to realize breakthroughs in the optoelectronic properties of 2D perovskites, to deepen the scientific understanding of the fundamental mechanism between macroscopic properties and microscopic structures, and to expand their practical applications in optoelectronic and photonic devices. Original works combining modelling methods and experimental validation are highly welcome.

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. Crystals 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 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.
