Measuring electro-mechanical properties of thin films on polymer substrates
Electromechanical properties of metal films are studied with in-situ AFM-4PP tensile straining. AFM characterizes the surface damage and 4PP measures the resistance under tensile strain. The difference between local film necking and through thickness cracks can be made. It will be shown when the strain is removed, cracks bridge and the resistance decreases.
