摘要:

The wide variety of technological applications of carbon based-materials from diamond, graphene, organic electronic devices have triggered intensive studies of these materials worldwide. Understanding of the electronic structure and their interface properties of these functional materials is crucial for their technological applications. Synchrotron-based spectroscopies with tunable light source have a significant advantage in the investigation of opto-electronic/magnetic properties of materials, in which electronic properties related to the occupied, unoccupied states, and individual molecular valence orbitals can be probed by, e.g., photoemission, angle-dependent x-ray adsorption, resonant x-ray photoemission spectroscopies, etc. Furthermore, the magnetic information can be approached by e.g., x-ray magnetic circular dichroism. In this talk, I will give a brief introduction about the synchrotron-based electron/x-ray spectroscopy, then present our studies of organic interface properties with interface engineering, pi-conjugated organic materials bonded on nanocrystalline diamond upon tailoring electronic properties, and magnetic properties of organic spintronics.
