Modeling charge transport in graphene nanoribbons and carbon nanotubes using a Schrödinger-Poisson solverWe report on the electromechanical robustness of graphene in an extreme condition of deformation: uniaxial bending. A large-angle-bent graphene monolayer was obtained with a predefined template. Structural/mechanical analysis is conducted, followed by electronic transport measurement. Raman spectroscopy analysis suggests negligible strain in the significantly bent graphene, showing mechanical robustness of the two-dimensional carbon nanostructure. The impact on band structure with respect to key deformation parameters ͑bending angle and curvature radius͒ were investigated using sp 3 tight-binding simulation. Results show insignificant local band modification at bending locations. Even with extreme deformation, excellent carrier mobility in monolayer graphene is preserved.
