摘要：
Organic field-effect transistors (OFETs) based on interconnected nanowire networks of P3HT have been successfully fabricated by using a mixed-solvent method. The nanowire network density can be tuned by controlling the anisole/chlorobenzene ratio of mixed solvents. The obtained field-effect mobility, threshold voltage and the ratio of on-state current and off-state current (I-on/I-off) was 0.0435 cm(2)/V s, -10 V and 1.75 x 10(4), respectively. The three-dimensional and interconnected nanowire structure of the networks can enhance the charge transport in P3HT.
