A Generalized Read-Shockley Model and Large Scale Simulations for the Energy and Structure of Graphene Grain Boundaries
Ashivni Shekhawat, Colin Ophus, Robert O. Ritchie
The grain boundary (GB) energy is a quantity of fundamental importance for understanding several key properties of graphene. Here we present a comprehensive theoretical and numeric…
Toughness and damage tolerance of fractal hierarchical metamaterials
Ashivni Shekhawat
We present a theory for the toughness, damage tolerance, and tensile strength of a class of hierarchical, fractal, metamaterials. We show that the even though the absolute toughnes…
Deformation of crystals: Connections with statistical physics
James P. Sethna, Matthew K. Bierbaum, Karin A. Dahmen +12
We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical physics community, and a broad introduction into the statistical theories of forced rigid…
Toughness and Strength of Nanocrystalline Graphene
Ashivni Shekhawat, Robert O. Ritchie
Pristine monocrystalline graphene is claimed to be the strongest material known with remarkable mechanical and electrical properties. However, graphene made with scalable fabricati…
Large-Scale Experimental and Theoretical Study of Graphene Grain Boundary Structures
Colin Ophus, Ashivni Shekhawat, Haider I Rasool +1
We have characterized the structure of 176 different single-layer graphene grain boundaries using 1000 experimental HRTEM images using a semi-automated structure processing rout…
