Graphene modifications using swift heavy ions

Since its discovery in 2004, graphene research attracts great attention and its numerous applications are envisaged in the near future [1]. In this contribution, we show how swift heavy ions can be used as a tool for controled modification of graphene on the nanoscale. Very recently, it was demonstrated that passage of swift heavy ions delivered from cyclotron (GANIL, France) at grazing incidence with respect to the graphene results in unzipping and folding of exfoliated graphene [2]. These modifications can be produced in controlled manner since number of pores is determined by ion fluence. Here we show how less energetic swift heavy ions delivered from 6 MV Tandem Van de Graaff accelerator (Ruđer Bošković Institute, Zagreb) can be used for graphene modifications as well. In addition, we present first results on swift heavy ion induced modifications on other 2D materials. [1] K.S. Novoselov et al., A roadmap for graphene, Nature 490 (2012) 192 [2] S.
