Special Issue Information
Dear Colleagues,
Low-dimensional quantum materials, such as two-dimensional (2D) graphene, one-dimensional (1D) nanowires, and zero-dimensional (0D) quantum dots, have attracted considerable attention in physics, chemistry, and materials science. Their distinctive electronic, optical, and magnetic properties stem from quantum confinement effects and reduced symmetry, making them promising candidates for advanced technologies like electronics, spintronics, and quantum computing. As research advances, these materials are expected to play a key role in developing smaller, faster, and more efficient devices across various applications.
The discovery of the 2D electron gas (2DEG) in semiconductor heterostructures, which led to the observation of the integer and fractional quantum Hall effects, illustrates the significance of low-dimensional systems. Similarly, the interface between complex oxides has been found to host a superconducting 2DEG, offering new opportunities to explore the physics of strongly correlated electrons confined in 2D. The family of 2D materials has recently expanded beyond graphene to include transition metal dichalcogenides (e.g., MoS₂, WSe₂), phosphorene, MXenes, and twisted multi-layer graphene. These materials open new avenues for discovering fundamental physics and developing next-generation applications.
One-dimensional systems like nanowires and nanotubes enable highly directional electron transport. Carbon nanotubes, semiconductor nanowires, and complex oxide nanowires are promising for nanoelectronics and sensors. Quantum dots, nanometer-sized semiconductor particles, confine electrons in all three spatial dimensions, resulting in discrete energy levels and size-tunable optical properties. These properties make quantum dots valuable for applications in biological imaging and photovoltaics. Notable, the 2023 Nobel Prize in chemistry recognized the discovery and development of quantum dots.
In this Special Issue, “Research on Low-Dimensional Quantum Materials”, we aim to summarize experimental and theoretical advancements in the field, discuss the remaining challenges, and provide roadmaps for future research.

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 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.
