Highly Sensitive, Air‐Stable Photodetectors Based on Single Organic Sub‐micrometer Ribbons Self‐Assembled through Solution Processing

Highly sensitive, air-stable photodetectors based on single sub-micrometer organic crystalline ribbons self-assembled and deposited on the substrate via simple solution processing are achieved on both glass substrates and flexible substrates. The photoconductivity gain is about 1.3 × 103, while the responsivity is about 420 A W−1 at a field of 2 × 104 V cm−1. The highest on/off ratio reaches around 1000.
