What is it about?
strain creates ripples, but also ripples lead to band gap opening, which is fundamental for using Graphene as a material for electronics. This is a modelling study supported by experimental TEM.

Why is it important?
If the predictions can be realised in practice, Graphene would get a lot of commercial applications in electronics
Perspectives
there are several aspects of importance. Firstly we created a unique and very advanced empirical potential for doing molecular dynamics of Graphene, with the prospect of performing phonon calculations too, of interest to modellers and theorists. Secondly we predict the link between strain and ripples, and between ripples and badgap opening, which is a first and of interest to technologists. Thirdly, the plots and associated video are really cool!!!
