Materials (ISSN: 1996-1944) has launched the Section “Thin Films and Interfaces”. Thin film materials are widespread for technological applications, spanning from electronics through medicine. Thin film materials can exhibit a greater number of vastly different structural, chemical, electrical, optical, and mechanical properties compared to their corresponding bulk counterparts due to the choice of substrate or underlying material, the material deposition and fabrication process, and the resulting variations in the crystal phase, disorder and defects within poly-/nano-crystalline and amorphous materials, strain, and composition. The very nature of thin films involves the formation of interfaces, including that with the substrate, underlying or overlying layers, and/or the ambient. These interfaces and interfacial regions may exhibit additional variations due to confinement, bonding configurations, chemical composition, exposure to ambient, physical mixing, and the morphology present.

We are pleased to present the 2023 Editor’s Choice Articles, a carefully curated list of high-quality articles from the Section “Thin Films and Interfaces” listed below.
