Description
It was suggested that breakdown initiation is directly linked to plastic activity in electrodes and specifically to dislocation motion leading to surface evolution. However, the exact mechanism by which various surface and subsurface electrode structural features affect the highest sustainable fields remains unknown. In the present talk, we will show the characteristic features of “intrinsic” dislocation structures observed in the hard and soft Cu electrodes prior to the BD tests. In addition, we will characterize the details of dislocation structures developed in the post-BD samples. The interrelation of pre- and post-BD dislocation landscape and the possible mechanism of dislocation –related field enhancement will be discussed.
