Auger-Electron Analysis of Oxide Layers on Copper

Aim of this project is to (i) proof and (ii) quantify the thickness of possible oxide layers on Cu and CuAl systems. The experiments are planned within a large scale micromechanical investigation on dislocation nucleation at coherent twin boundaries, performed at the Max-Planck-Institut für Eisenforschung. So far, using nanoindentation, we have shown that grain boundaries might act as frequent sources of dislocations. However, to ultimately proof this we need to proof the absence of surface oxides.
