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.
