Silicatene una Graphene
Published in Shamil Shaikhutdinov, Introduction to Ultrathin Silica Films Silicatene and Others, 2022
Single-layer materials have recently received enormous attention owing to their two-dimensional (2D) character leading to peculiar physical and chemical properties very different from or even missing in their three-dimensional (3D) counterparts. The most famous one—graphene1—triggered a quest for other truly 2D materials. In fact, free-standing single layers of Si and Ge had been predicted on theoretical grounds a while ago.2 Later they were discovered experimentally, so far only supported on metal substrates, and received the names “silicene” and “germanene,” respectively.3–6 The studies have been extended to a Sn single layer called “stanene.”7 Note, however, that possible incorporation and mixing with substrate atoms in these layers remains the subject of debate.8,9

In 2011, a paper on the fabrication of single-layer MoS2 attracted the attention to the research on other 2D materials [98]. The IRDS and the ITRS has mentioned other 2D amterials as candidates for future electronics [3]. In fact, in 2005, the Novoselov-Geim group reported the preparation of single-layer materials (for instance, MoS2, MoSe2, MoT e2 and WS2) other than graphene [99]. The experimental MoS2 FETs show reasonable mobilities and an excellent ON-OFF ratio [98, 100]. On the theoretical work, simulation results qualitatively confirm the experimental results and predict very high ON-OFF ratios with monolayer dichalcogenide channels [101, 102].
The correlation between structure, multifunctional properties and application of PVD MAX phase coatings. Part III. Multifunctional applications
Published in Surface Engineering, 2020
Numerous other single layer materials such as TiC, CrN, ZrN, MoN [e.g. 91] or Diamond Coatings [92] were investigated for their erosion properties. However, these all showed limited protection. In addition, it is unlikely that a single material coating can fit all aspects of the protection scheme discussed previously where it would have to have either metallic or ceramic properties in one coating.
