Advancements in Low-Dimensional Materials: Focus on Detailed Methodologies

Dear Colleagues,

The study of low-dimensional materials began to gain prominence with the discovery of graphene in 2004, a single layer of carbon atoms with exceptional electrical, thermal, optical, and mechanical properties. Before this, carbon nanotubes, discovered in 1991, had already showcased remarkable strength and conductivity as one-dimensional materials. Quantum dots, zero-dimensional nanoparticles, emerged in the 1980s, offering size-tunable electronic and optical properties due to quantum confinement.

It is worth mentioning that the exploration of two-dimensional materials expanded with the discovery of monolayer transition metal dichalcogenides like monolayer molybdenum disulfide (MoS₂) around 2011, which displayed versatile electronic and optical properties. The study of topological insulators introduced materials with insulating bulk states but conductive surface states, enriching our understanding. Further, the integration of various 2D materials into heterostructures, including twisted heterostructures in the 2010s, led to new phenomena and potential applications, marking significant progress in nanotechnology.

As will be seen in this Special Issue, low-dimensional materials exhibit a wide range of new properties that can be employed to fabricate improved and novel devices. The ongoing research on these materials is advancing electronics, materials science, and related fields. We would like you to consider submitting a manuscript in this field that provides detailed and rigorous methodologies or processes, as these are crucial for advancing the field and ensuring replicability and robustness in research findings.

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. Processes 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 2400 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.
