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…
Failure mechanisms of single-crystal silicon electrodes in lithium-ion batteries
Feifei Shi, Zhichao Song, Philip N. Ross +3
Long-term durability is a major obstacle limiting the widespread use of lithium ion batteries (LIBs) in heavy-duty applications and others demanding extended lifetime. As one of th…
Exceptional damage-tolerance of a medium-entropy alloy CrCoNi at cryogenic temperatures
Bernd Gludovatz, Anton Hohenwarter, Keli V. S. Thurston +4
High-entropy alloys are an intriguing new class of metallic materials that derive their properties from being multi-element systems that can crystallize as a single phase, despite…
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…
