Synthetic carbon allotropes are the focus of the project, in order to conduct strong field physics and matter wave experiments with free electrons of low energy (eV range). The project is divided into two work packages (WPs). In WP1 we investigate coherent electron dynamics in graphene and graphene nanocontacts on ultrafast (sub-) femtosecond time scales. In WP2 we plan to holographically image functionalized carbon nanotubes using coherent low-energy electron diffraction. In WP2 we also investigate the ultrafast electron emission of nanocrystalline diamond tips, which should enable extremely good electron beam properties.

合成碳同素异形体是该项目的重点，目的是用低能(EV范围)的自由电子进行强场物理和物质波实验。该项目分为两个工作包(WPS)。在WP1中，我们研究了超快(亚)飞秒时间尺度上石墨烯和石墨烯纳米接触中的相干电子动力学。在WP2中，我们计划使用相干低能电子衍射对功能化碳纳米管进行全息成像。在WP2中，我们还研究了纳米晶金刚石尖端的超快电子发射，这将使极好的电子束性能成为可能。
