Exciton dissociation in polymer field-effect transistors studied using terahertz spectroscopy
We have used terahertz time-domain spectroscopy to investigate photoinduced charge generation in conjugated polymer field-effect transistors. Our measurements show that excitons dissociate in the accumulation layer under the application of a gate voltage, with a quantum efficiency of ∼0.1 for an ave...
