Mechanical Cycling Stability of Organic Thin Film Transistors on Shape Memory Polymers



original image

Organic thin film transistors on shape memory polymers are fabricated by full photolithography. Devices show high mobility (0.2 cm2 V−1 s−1) and close to zero threshold voltage (-4.5 V) when characterized as fabricated. After 1, 10, and 100 deformation cycles and in a deformed, metastable shape memory transition state, changes in mobility and Vth are measured and indicate sustained device functionality.
