Abstract: A method for enhancing the performance of pentacene organic field-effect transistor (OFET): an n-type semiconductor thin film was set as a buffer layer between pentacene and polymer electret in the OFET with the structure of gate-electrode/insulating layer/polymer/pentacene/source (drain) electrode. The thickness of n-type organic buffer layer is 1˜100 nm. The induced electrons at the interface lead to the reduction of the height of the hole-barrier formed at the interface, thus effectively reducing the programming/erasing (P/E) gate voltages of pentacene OFET. The widened distribution region of positive space charges caused by ionized donors in n-type organic buffer layer effectively restricts the back-transfer of holes from polymer to pentacene, thus improving the performance of pentacene OFET, such as the P/E speeds, P/E endurance and retention characteristics.

In this way, the method forms a chromatic aberration to localize the dark-colored cigarette sample, thereby testing the burning performance of the dark-colored cigarette sample.
