“…Interestingly, this crystal structure is the nanoscale analog of the re-entrant hinged structure proposed by Lakes [75] for NPR in bulk materials. Other puckered 2D materials, such as orthorhombic arsenic, would also be expected to exhibit NPR, which was recently confirmed by Han et al [76]. In addition to puckered 2D materials, graphene also exhibits intrinsic NPR, though for tensile strains exceeding about 6% [77].…”

Since the first successful synthesis of graphene just over a decade ago, a variety of twodimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitride, etc.) have been discovered. Among the many unique and attractive properties of 2D materials, mechanical properties play important roles in manufacturing, integration and performance for their potential applications. Mechanics is indispensable in the study of mechanical properties, both experimentally and theoretically. The coupling between the mechanical and other physical properties (thermal, electronic, optical) is also of great interest in exploring novel applications, where mechanics has to be combined with condensed matter physics to establish a scalable theoretical framework. Moreover, mechanical interactions between 2D materials and various substrate materials are essential for integrated device applications of 2D materials, for which the mechanics of interfaces (adhesion and friction) has to be developed for the 2D materials. Here we review recent theoretical and experimental works related to mechanics and mechanical properties of 2D materials. While graphene is the most studied 2D material to date, we expect continual growth of interest in the mechanics of other 2D materials beyond graphene.

“…Stimulated by the many intriguing properties and practical applications discussed above, the investigation of materials with negative Poisson's ratio has attracted considerable interest. So far, enormous progress (as summarized in Figure ) has been made in realizing a negative Poisson's ratio in various advanced materials, such as organic materials, mixed‐valence materials, oxides, low‐dimensional films, and man‐made materials ranging from the macroscopic level (honeycombs, foams, ceramics, composites, or others) down to the microscopic level (microporous polymers, molecular auxetics, and low‐dimensional materials). In previous reviews, attention has mainly been focused on man‐made synthetic materials with special structures (as shown Figure ) spanning from the molecular level to the macroscopic scale .…”

Materials with negative Poisson's ratio attract considerable attention due to their underlying intriguing physical properties and numerous promising applications, particularly in stringent environments such as aerospace and defense areas, because of their unconventional mechanical enhancements. Recent progress in materials with a negative Poisson's ratio are reviewed here, with the current state of research regarding both theory and experiment. The inter-relationship between the underlying structure and a negative Poisson's ratio is discussed in functional materials, including macroscopic bulk, low-dimensional nanoscale particles, films, sheets, or tubes. The coexistence and correlations with other negative indexes (such as negative compressibility and negative thermal expansion) are also addressed. Finally, open questions and future research opportunities are proposed for functional materials with negative Poisson's ratios.

“…Besides the intensely studied graphene, single-and few-layer hexagonal boron nitride (hBN) [2][3][4], molybdenum dichalcogenides such as MoS 2 and MoSe 2 [5][6][7][8], and recently exploited phosphorene [9][10][11][12][13][14][15][16] and arsenene [17][18][19][20] have been attracting intense attention. Researches on these 2D materials will undoubtedly continue to be one of the hottest topics for long time.…”

engineering in van der Waals heterostructures of blue phosphorene and MoS 2 : A first principles calculation, Journal of Solid State Chemistry, http://dx.Abstract Blue phosphorene (BP) was theoretically predicted to be thermally stable recently. Considering its similar in-layer hexagonal lattice to MoS 2 , MoS 2 could be appropriate substrate to grow BP in experiments. In this work, the van der Waals (vdW) heterostructures are constructed by stacking BP on top of MoS 2 . The thermal stability and electronic structures are evaluated based on first principles calculations with vdW-corrected exchange-correlation functional. The formation of the heterostructures is demonstrated to be exothermic and the most stable stacking configuration is confirmed. The heterostructures BP/MoS 2 preserve both the properties of BP and MoS 2 but exhibit relatively narrower bandgaps due to the interlayer coupling effect. The band structures can be further engineered by applying external electric fields. An indirect-direct bandgap transition in bilayer BP/MoS 2 is demonstrated controlled by the symmetry property of the built-in electric dipole fields.
