Phototransistor Properties of Pentacene Organic Transistors with Poly(methyl methacrylate) Dielectric Layer
The phototransistor properties of pentacene organic transistors with a poly(methyl methacrylate) dielectric layer have been investigated. It was found that as the intensity of incident light increased, drain current gradually increased and threshold voltage shifted by degrees towards the positive direction, because of the higher number of more photons provided by incident light with a high intensity leading to a higher carrier density in the channel. Moreover, the prepared organic transistors showed a photocurrent response opposite to the absorption spectrum of pentacene. The photoresponse time of the pentacene transistor was determined to be shorter than 0.03 s.
