“…Since the discovery of graphene, mechanical exfoliation of 2D layered materials from bulk parent materials has been the optimal preparation method for investigating their intrinsic physical and chemical properties. [78,[82][83] The main step of this top-down method is illustrated as follows: first the single crystal bulk material is attached to the adhesive on the Scotch tape and then another piece of tape is placed on the other side of the material, following by peeling off the two pieces of tape for several times; the freshly cleaved thin flake on the Scotch tape is then attached to a clean, flat substrate (generally 300 nm SiO 2 /Si substrate); finally few layers or monolayer material can be obtained on the target substrate. Actually, mechanical cleavage has been widely used as a facile technique to obtain few-layer ReX 2 with high quality, clean surface, and relatively large area for studying their fundamental properties and potential applications.…”

The rise of 2D transition-metal dichalcogenides (TMDs) materials has enormous implications for the scientific community and beyond. Among TMDs, ReX 2 (X = S, Se) has attracted significant interest regarding its unusual 1T′ structure and extraordinary properties in various fields during the past 7 years. For instance, ReX 2 possesses large bandgaps (ReSe 2 : 1.3 eV, ReS 2 : 1.6 eV), distinctive interlayer decoupling, and strong anisotropic properties, which endow more degree of freedom for constructing novel optoelectronic, logic circuit, and sensor devices. Moreover, facile ion intercalation, abundant active sites, together with stable 1T′ structure enable them great perspective to fabricate high-performance catalysts and advanced energy storage devices. In this review, the structural features, fundamental physicochemical properties, as well as all existing applications of Re-based TMDs materials are comprehensively introduced. Especially, the emerging synthesis strategies are critically analyzed and pay particular attention is paid to its growth mechanism with probing the assembly process of domain architectures. Finally, current challenges and future opportunities regarding the controlled preparation methods, property, and application exploration of Re-based TMDs are discussed.

Several research groups have reported on the observation of superconductivity in bilayer graphene structures where single atomic layers of graphene are stacked and then twisted at angles forming Moiré superlattices. The characterization of the superconducting state in these 2D materials is an ongoing task. Here we investigate the pairing symmetry of bilayer graphene Moiré superlattices twisted at  = 1.05°, 1.10° and 1.16° for carrier doping states varied in the range of = 0.5 − 1.5 • 10 12 −2 (where superconductivity can be realized) by analyzing the temperature dependence of the upper critical field Bc2(T) and the self-field critical current Jc(sf,T) within currently available models for single-and two-band s-, d-, pand d+id-wave gap symmetries. Extracted superconducting parameters show that only s-wave and a specific kind of p-wave symmetries are likely to be dominant in bilayer graphene Moiré superlattices. More experimental data is required to distinguish between the s-and remaining p-wave symmetries as well as the suspected two-band superconductivity in these 2D superlattices.
