Special Issue Information

Dear Colleagues,

We are delighted to extend to you an invitation to contribute your original research to our Special Issue on “Functional Two-Dimensional Materials, Thin Films and Coatings”. This Special Issue is dedicated to exploring the preparation, characterization, properties, and applications of 2D materials, thin films, and coatings.

In recent years, nanoscale materials, thin films, and coatings have gained significant traction across various disciplines owing to their exceptional optical, electrical, magnetic, thermal, and mechanical properties, which markedly differ from those of bulk materials. The distinctive characteristics of 2D materials, such as their high surface area-to-volume ratio, surface charge, structural anisotropy, and tunable functionalities, have led to their widespread application in diverse fields such as materials science, optoelectronics, microscopy, engineering, and biomedical science.

This Special Issue endeavors to showcase recent advancements and address emerging challenges in the realms of nanomaterial science, engineering, and nanotechnology. We specifically aim to elucidate the interplay between advanced fabrication techniques, material properties, and practical applications. We warmly welcome contributions encompassing experimental, theoretical, computational, or other research of nanomaterials, spanning from 2D materials to hard (inorganic) and soft (polymeric and biological) thin films and coatings.

Our goal is to provide a platform for disseminating the latest developments in the characterization, synthesis, and applications of 2D materials, functional thin films and coatings, as well as hybrid materials/ heterostructures. We encourage submissions that explore novel preparation, transfer, and assembly techniques, as well as those that highlight industrially scalable techniques.

We look forward to receiving your valuable contributions to this exciting Special Issue.

We report a two-step growth process of MoS2 nanoflakes using a low-pressure chemical vapor deposition technique. In the first step, a MoS2 layer was synthesized on a c-plane sapphire substrate. This layer was subsequently re-evaporated at a higher temperature to form mono- or few-layer MoS2 flakes. As a result, the close proximity re-evaporation enabled the growth of pristine MoS2 nanoflakes. Atomic force microscopy analysis confirmed the synthesis of nanoclusters/nanoflakes with lateral dimensions of over 10 μm and a flake height of approximately 1.3 nm, demonstrating bi-layer MoS2, whereas transmission electron microscopy analysis revealed triangular MoS2 nanoflakes, with a diffraction pattern proving the presence of single crystalline hexagonal MoS2. Raman data revealed the typical modes of high-quality MoS2 nanoflakes. Finally, we presented the photocurrent dependence of a MoS2-based photoresist under illumination with light-emitting diode of 405 nm wavelength. The measured current–voltage dependence across various luminous flux outlined the sensitivity of MoS2 to polarized light and thus opens further opportunities for applications in high-performance photodetectors with polarization sensitivity.
