'Guided' Fractures in Graphene Mechanical Diode-like Structures
Levi C. Felix,
Douglas S. Galvao
Abstract:The concept of diode is usually applied to electronic and thermal devices but very rarely for mechanical ones. A recent proposed fracture rectification effect in polymer-based structures with triangular voids defects has motivated us to test these ideas at the nanoscale using graphene membranes. Using fully-atomistic reactive molecular dynamics simulations we showed that a robust rectification-like effects exists. The fracture can be 'guided' to easier propagate along one specific direction than its opposite. … Show more
