Abstract

Fabrication of truly flexible optoelectronic devices, such as flexible displays and flexible photovoltaics, is highly dependent on the mechanical integrity of individual thin inorganic/organic hybrid device components. A common feature of almost all thin composite film components for flexible optoelectronic applications is indium tin oxide (ITO) coated on polyester. The mechanical mismatch of the ITO ceramic coating, a few tens of nm thick, with the polyester, either polyethylene terephthalate (PET) or polyethylene naphthalate (PEN), 125 μm thick, causes the flexible functional structure to fail at moderately low strains under various, externally applied, stress states. It is therefore important to assess the mechanical integrity of such hybrid systems experimentally. We report on the electromechanical behavior of such hybrid systems.
