Abstract
Highly light-responsive ink-jet printed 6,13-bis(triisopropylsilylethynyl) (TIPS) pentacene thin films were investigated as a photo-sensing active layer by employing suspended top-contact phototransistors. Under a steady-state illumination, the suspended top-contact TIPS-pentacene organic phototransistors have shown a current modulation of 106-107, resulting in dynamic range of 120 dB even in the low-molecular ordered ink-jet printed films. These results suggest that the suspended top-contact phototransistors based on ink-jet printed TIPS-pentacene can be a new promising candidate for low-cost and high-performance photo-sensing element for digital imaging applications.
