摘要：
Field emission measurements on diamond like carbon (DLC) films with different amounts of sp(3) and sp(2) carbon were carried out. Depending on the amount of sp(2) carbon in the film, activated and non-activated Fowler-Nordheim like emission could be observed. The emission spots were investigated using a combination of AFM and STM, by simultaneously measuring the topography and the conductivity of the samples. In the case of sp(2) rich DLC films we could observe that the emission originates from highly conducting inclusions of sp(2) carbon in a matrix of insulating sp(3) carbon. These inclusions are already existing on the sp(2) sample by the deposition process itself and are formed by the activation on the sp(3) rich sample.
