Interface structure is a basic problem in interface and surface science. It is usually indicated by atomic positions for an ideal interface. But this way is sometimes unsuitable for a mismatch interface, because there are too many atoms under consideration, whose coordinates may confuse our mind in understanding the interface structure. In this case, a 'dislocation representation' is introduced. A misfit dislocation network is used as an effective representation of the interface structure. However, there are two questions on this topic. How to determine the dislocation network structure? And how to relate it to interface dynamics? In this paper, we work on the first question and make an effort to build up the 'dislocation representation' for metal/Al(2)O(3) interfaces.
