Since the first successful synthesis of graphene just over a decade ago, a variety of two-
dimensional (2D) materials (eg, transition metal-dichalcogenides, hexagonal boron-nitride …

Grain size has a profound effect on the mechanical response of metals. Molecular dynamics
continues to expand its range from a handful of atoms to grain sizes up to 50 nm, albeit …

Pristine monocrystalline graphene is claimed to be the strongest material known with
remarkable mechanical and electrical properties. However, graphene made with scalable …

Since the success of monolayer graphene exfoliation, two-dimensional (2D) materials have
been extensively studied due to their unique structures and unprecedented properties …

There are prevailing concerns with the critical dimensions when conventional theories break
down. Here we find that the Griffith criterion remains valid for cracks down to 10 nm but …

Abstract Two-dimensional (2D) materials, such as graphene, hexagonal boron nitride (hBN),
phosphorene, transition metal dichalcogenides (eg, MoS 2, WS 2, etc.), metal oxides (eg …

Fracture is one of the most prominent concerns for large scale applications of graphene. In
this paper, we review some of the recent progresses in experimental and theoretical studies …

Abstract Two-dimensional (2D) materials such as graphene and molybdenum disulfide et al.
offer significant new prospects for electronics, optics, and biosensing applications due to …

We investigate the mechanical properties of polycrystalline graphene deforming under
uniaxial tension by using molecular dynamics simulations, focusing on the effects of grain …

Pristine monocrystalline molybdenum disulfide (MoS2) possesses high mechanical strength
comparable to that of stainless steel. Large-area chemical-vapor-deposited monolayer …
