Abstract:
Inkjet-printed short-channel polymer transistors exhibit a high performance (μavg = 1.20 cm(2) V(-1) s(-1) ). With a 50 μm orifice nozzle, polymer transistors with a sub-micrometer (700 nm) channel length are mass-fabricated with good uniformity and reproducibility. In addition, owing to the device geometry, an ultrahigh photoresponsivity up to 10(6) A W(-1) is achieved, which realizes economical, lithography-free photodetectors.
