Experimental Determination of Surface Stress Changes in Electrochemical Systems – Possibilities and Pitfalls

G. G. Láng, N. S. Sas and S. Vesztergom

In the present paper, the different techniques used for the determination of changes of surface stress of solid electrodes, as well as the kind and quality of information that can be achieved using these methods are discussed. The most important methods are briefly reviewed and advantages/drawbacks highlighted. Special attention is paid to issues related to the use of the “bending beam” (“bending cantilever”, “laser beam deflection”, “wafer curvature”, etc.) methods. Recent development in these techniques has been introduced and discussed.
