摘要: All-polymer phototransistors were fabricated using both glass and flexible plastic film substrates by employing bulk heterojunction channel layers of p-type polymer (P3HT) n-type (THBT-ht). The devices could detect the entire visible light because sense photons in deep red parts (>650 nm). responsivity was higher at lower intensity, while it be controlled varying gate and/or drain voltages. Similar performances measured for all-polymer with a bottom-source/drain top-gate electrode configuration.
