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.

该项目研究了一种生产和操纵石墨烯纳米结构的创新方法。支撑和悬浮的石墨烯将用高能离子照射，即具有高动能的快速重离子和具有高势能的慢速高电荷离子。这两种抛射体类型在石墨烯以及支撑材料中诱导超强度的电子激发。预计极端的能量密度将导致纳米尺度的结构变化，可以利用这些结构变化来创建定义的石墨烯纳米结构。 将详细分析在各种条件下辐照的石墨烯样品，以优化离子束参数，以适应潜在的应用。
