Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials have been at the core of intense research and development since the isolation of the first two-dimensional material—graphene. Caused by 2D confinement, 2D materials opened a completely novel chapter of the study of condensed matter. Novel extraordinary properties are discovered almost daily. Meanwhile, the vast amount of research leaves little doubt about the potential of 2D materials due to their unique topological, optical, electronic, magnetic, thermal, and mechanical properties. The large family consisting of 2D materials opens unprecedented opportunities for both fundamental science and various technological applications.

Although opportunities abound, significant challenges remain in the use of 2D materials. Currently, there are no available integrated chips or enabled products based on 2D materials. Furthermore, methods for enabling large-scale production with high-quality and controlled structures are still lacking. While assembling different 2D layers offers unique ways to control various phenomena including optical, electrical, thermal, magnetic, and topological phenomena, issues such as device-to-device variations, reliability, stability, and performance of 2D heterostructures in electronic and optoelectronic applications still need to be addressed. Nonetheless, 2D materials remain a promising research direction and have the potential to make a significant contribution. Besides electronic application, 2D materials are expected to facilitate the development of sustainable technology, such as energy storage, conversion, and catalysis. There are still many applications of 2D materials that we should develop. With the need to accelerate materials discovery and design, new technologies including machine learning and artificial intelligence need to be employed. Methodological development in theoretical modelling and computational algorithms, in close interaction with experiments, become necessary for the discovery of the extraordinary properties of 2D materials.

At Crystals, we wish to support research providing insight into the path toward addressing the challenges that hinder the development of 2D materials. Crystals is ideally a forum for the advancement of our understanding of the growth, processing, and characterization of materials. Additionally, their mechanical, chemical, electronic, magnetic, optical, and topological properties and their diverse applications are all considered to be of importance.

With a view to achieving these goals, this Special Issue will focus on new ideas and advanced research in 2D materials and will cover a wide range of topics. Both original research and review articles are welcomed, with areas of interest including, but not limited to:

  • Synthesis, fabrication, characterization, and properties of 2D materials.
  • Applications involving 2D materials.
  • Theoretical calculation methods involving 2D materials.

We report the results of atomistic simulations of friction between two-dimensional titanium carbide Ti2C (MXene) and a silver nanoparticle located on its surface. Numerical experiments were performed within classical molecular dynamics methods using a previously developed scheme for simulations of interactions between MXenes and metal nanoparticles. In the computer experiments performed, both tangential and shear forces were applied to the Ag nanoparticle to initiate its sliding on the surface of the Ti2C MXene. During the simulations, the nanotribological parameters of the studied system, such as the friction force, contact area, friction coefficient, and tangential shear, were computed. It is shown that, for the studied system, the friction coefficient does not depend on the velocity of nanoparticle movement or the contact area. Additionally, the sliding friction of the nanoparticle on the flexible substrate was considered. The latter case is characterized by a larger friction coefficient and contact area due to the formation of wrinkles on the surface of the substrate. Full article
