Summary: Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle creates a moire superlattice, which has properties that are markedly modified from (and at times entirely absent in) the 'parent' materials. Moire materials have advanced the study and engineering of strongly correlated phenomena and topological systems in reduced dimensions. Understanding electronic phases like superconductivity necessitates precise control in fabrication, involving the rotational alignment of two atomically thin layers with high angular precision.

Summary: Borophene, a crystalline monolayer boron sheet, has the potential to be used in flexible electronics, energy storage, and catalysis due to its polymorphism. Synthesized on a square-lattice Cu(100) surface, borophene forms micrometre-scale single-crystal domains with a new polymorph different from previous reports.

Summary: 2D semiconducting transition metal dichalcogenides are a promising class of materials that have unique properties, including large exciton binding energies. The ability to control interlayer excitons in van der Waals heterostructures provides opportunities for spin and valley degree of freedom manipulation in solid-state devices. This review discusses recent progress in device architectures and engineering techniques for tailored properties of interlayer excitons.

Summary: Many-body interactions between carriers play a crucial role in correlated physics. This study demonstrates the ability to highly tune spin-spin interactions between moire-trapped carriers using optical excitation, resulting in ferromagnetic order in WS2/WSe2 moire superlattices. The observed phenomenon adds a dynamic tuning knob to the rich many-body Hamiltonian of moire quantum matter.

Summary: This study reports the direct observation of two new plasmon modes in macroscopic twisted bilayer graphene (tBLG) with a highly ordered moiré superlattice. These modes include chiral plasmons arising from the uncompensated Berry flux of the electron gas under optical pumping, and slow plasmonic modes resulting from interband transitions in AB-stacked domains. These findings are important for understanding the electromagnetic dynamics of small-angle tBLG and enabling strong light-matter interactions in the mid-wave infrared spectral window.

Summary: This study reports the successful nucleation of bilayer molybdenum disulfide (MoS2) on c-plane sapphire, achieving uniformity in the nucleation process. The design of atomic terrace height on c-plane sapphire allows for an edge-nucleation mechanism and the coalescence of MoS2 domains into continuous, centimeter-scale films. Field-effect transistor devices based on bilayer MoS2 channels show improved mobility and reduced variation compared to monolayer films.

Summary: Borophene, a monatomic layer of boron atoms, has versatile properties but faces challenges in growth and characterization on metal substrates. A strategy utilizing step-edges on an h-BN substrate has been devised to enable boron epitaxial assembly and reduce the nucleation barrier, making borophene more accessible for testing or application on insulating substrates.

Summary: Borophene, a two-dimensional layer of elemental boron, shows rich polymorphism and potentially interesting properties, but its growth on metal substrates has been limited to monolayers. A new method of layer-by-layer borophene growth on Ru(0001) substrates has been developed, allowing for coverage of up to two atomic layers and providing a new avenue for growing high-quality few-layer borophene.

Summary: The study presents a generic methodology for large-area integration of 2D materials through adhesive wafer bonding, utilizing equipment, processes, and materials readily available in large-scale semiconductor manufacturing lines. This approach is suitable for back end of the line integration of 2D materials on top of integrated circuits, with the potential to accelerate progress in electronics, photonics, and sensing. Existing integration approaches for 2D materials often degrade material properties and are not compatible with industrial processing, highlighting the need for new strategies like adhesive wafer bonding.

Summary: This article assesses the material parameters and performance limits of hexagonal boron nitride (hBN) as a gate insulator, comparing experimental and theoretical tunnel currents through ultrathin layers of hBN and other 2D gate insulators. Despite its candidacy for many applications in 2D nanoelectronics, excessive leakage currents indicate that hBN is unlikely to be suitable for use as a gate insulator in ultrascaled CMOS devices.

Summary: The successful exfoliation of graphene has led to an increased focus on research of two-dimensional materials, which exhibit unique properties and potential applications. To achieve large-scale practical applications, wafer scale single crystalline 2D materials are crucial but face challenges in synthesis. Different routes for synthesizing these materials have been explored, with some successes in WSSC graphene, hBN, and MoS2, while growth of other WSSC 2D materials remains a significant challenge. Opportunities for future research in the synthesis of various wafer scale single crystalline 2D materials have been summarized.
