英文摘要	The performance of the single organic submicrometer ribbon based photodetector has been improved by one order of magnitude by combining a better crystalline structure with proper surface engineering, such as coating a dielectric layer PMMA or PS between the substrate and the organic semiconductor. The photoconductivity gain is as much as 1.3 x 10(4), the responsivity is about 4372 AW(-1) at the field of about 2 x 10(6) V m(-1), and the highest on/off ratio reaches 10(4). The extremely high gain is attributed to the high mobility and the long photo carrier's lifetime induced by the dielectric layer. (C) 2013 Elsevier B.V.
