Energy Barriers for Reversible Chain Scission and Healing under Tension with Displacement Control
Mohammad A. Ansari, Kenneth M. Liechti, Dmitrii E. Makarov +1
Polymer chain scission is a key mechanism for fracture of soft materials. It is well known from single-molecule force spectroscopy experiments that the critical condition for chain…
Interlayer Coupling and Strain Localization in Small-Twist-Angle Graphene Flakes
Vahid Morovati, Zhiming Xue, Kenneth M. Liechti +1
Twisted bilayer graphene (TBG) exhibits a wide range of intriguing physical properties, such as superconductivity, ferromagnetism, and superlubricity. Depending on the twist angle,…
A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond
Deji Akinwande, Christopher J. Brennan, J. Scott Bunch +17
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitrid…
Cavitation of Water by Volume-Controlled Stretching
Peng Wang, Wei Gao, Justin Wilkerson +2
A liquid subjected to negative pressure is thermodynamically metastable. Confined within a small volume, negative pressure can build up until cavities form spontaneously. The criti…
Entropic Effects of Thermal Rippling on van der Waals Interactions between Monolayer Graphene and a Rigid Substrate
Peng Wang, Wei Gao, Rui Huang
Graphene monolayer, with extremely low flexural stiffness, displays spontaneous rippling due to thermal fluctuations at a finite temperature. When a graphene membrane is placed on…
Interfacial adhesion between graphene and silicon dioxide by density functional theory with van der Waals corrections
Wei Gao, Penghao Xiao, Graeme Henkelman +2
Interfacial adhesion between graphene and a SiO2 substrate is studied by density functional theory (DFT) with dispersion corrections. The results demonstrate the van der Waals (vdW…
Effect of edge structures on elastic modulus and fracture of graphene nanoribbons under uniaxial tension
Qiang Lu, Rui Huang
Based on atomistic simulations, the nonlinear elastic properties of monolayer graphene nanoribbons under quasistatic uniaxial tension are predicted, emphasizing the effect of edge…
Effects of Mismatch Strain and Substrate Surface Corrugation on Morphology of Supported Monolayer Graphene
Zachary H. Aitken, Rui Huang
Graphene monolayers supported on oxide substrates have been demonstrated with superior charge mobility and thermal transport for potential device applications. Morphological corrug…
Excess energy and deformation along free edges of graphene nanoribbons
Qiang Lu, Rui Huang
Change of the bonding environment at the free edges of graphene monolayer leads to excess edge energy and edge force, depending on the edge morphology (zigzag or armchair). By usin…
Elastic Bending Modulus of Monolayer Graphene
Qiang Lu, Marino Arroyo, Rui Huang
A new formula for elastic bending modulus of monolayer graphene is derived analytically from an empirical potential for solid-state carbon-carbon bonds. Two physical origins are id…
