Operationally Stable Organic FETs With Bilayer Dielectrics on Low-Cost Flexible Polyimide Substrate

Organic FETs (OFETs) with bilayer dielectric poly(4-vinylphenol) (PVP)/HfO 2 and polyvinyl alcohol (PVA)/HfO 2 were fabricated on a flexible low-cost Kapton tape substrate with TIPS -pentacene:polystyrene as an active layer. The devices exhibited average and maximum field-induced mobility of 0.25(±0...
