We have shown in the past that fundamental properties of sliding interfaces like adhesion, friction, and ultimate strength, are closely connected to one another and the re-arrangement of charge at the interface [1-3]. We extended the previously presented approach for homogeneous interfaces to nearly arbitrary interfaces of crystalline surfaces, allowing us to treat heterogeneous interfaces of multi component systems [4].
In this talk we will present the fault tolerant and fully automatic workflow we developed, as well as initial results of the ongoing high-throughput studies we are conducting.
