Manipulation of graphene by high energy ions

该项目研究了一种制备和操作石墨烯纳米结构的创新方法。支撑和悬浮的石墨烯将被高能离子辐照，即具有高动能的快速重离子和具有高势能的慢速高电荷态离子。这两种类型的弹丸在石墨烯和载体材料中都会产生超强的电子激发。极端的能量密度有望导致纳米级的结构变化，这可以被用来创建定义的石墨烯纳米结构。在不同条件下辐照的石墨烯样品将被详细分析，以针对潜在的应用优化离子束参数。

This project investigates an innovative approach to produce and manipulate graphene nanostructures. Supported and suspended graphene will be irradiated with high energy ions, i.e. swift heavy ions with high kinetic energy and slow highly charged ions with high potential energy. Both projectile types induce ultra-intensive electronic excitations in graphene as well as in the support material. The extreme energy density is expected to result in structural changes on the nanometer scale which can be exploited to create defined graphene nanostructures. Graphene samples irradiated under various conditions will be analyzed in detail to optimize ion beam parameters with respect to potential applications.
