| Abstract: | Abstract— A high‐performance polymer thin‐film transistor fabricated on a paper substrate has been demonstrated. As a water barrier layer, parylene was coated on a paper substrate by using a vacuum deposition process. Using poly (3‐hexylthiophene) as an active layer, a polymer thin‐film transistor with a field‐effect mobility of up to 0.086 cm2/V‐sec and an on/off ratio of 104 was achieved. The fabrication of a polymer thin‐film transistor built on an inexpensive paper substrate is expected to open a channel for future applications in flexible and disposable electronics with extremely low cost. |
