We propose an international collaboration between two groups in South Korea expert in nanoscience and a group in Germany specializing in molecular beam surface scattering. The aim of the collaboration is to fabricate graphene in various modified forms using modern nanoscience and to study molecule-surface interactions with molecule beam surface scattering methods. Electronically nonadiabatic interactions, where the molecule's nuclear motion is coupled to the electrons of the solid, are now firmly established for the case of molecules at metal surfaces. A major aim of this proposal is to obtain the first observations of electronically nonadiabatic interactions of molecules at graphene surfaces. This will provide an important benchmark for understanding molecules at graphene surfaces, where up to now this is only considered within the Born-Oppenheimer approximation. Graphene's interesting and tunable electronic structure makes it a fascinating playground for such studies. Hydrogenation of graphene and controlled synthesis of multilayer graphene can be used to alter the electronic structure and observe changes in molecule surface interactions.

我们建议在韩国的纳米科学专家和专门从事分子束表面散射的德国的一个小组之间进行国际合作。合作的目的是利用现代纳米科学制造各种改性形式的石墨烯，并利用分子束表面散射方法研究分子-表面相互作用。电子非绝热相互作用，其中分子的核运动耦合到固体的电子，现在牢固地建立在金属表面的分子的情况下。这个建议的一个主要目的是获得在石墨烯表面的分子的电子非绝热相互作用的第一次观察。这将为理解石墨烯表面的分子提供一个重要的基准，到目前为止，这仅在Born-Oppenheimer近似中考虑。石墨烯有趣且可调的电子结构使其成为此类研究的迷人场所。石墨烯的氢化和多层石墨烯的受控合成可用于改变电子结构和观察分子表面相互作用的变化。
