Abstract

We fabricated organic thin film transistors (OTFTs) using soluble π-conjugated dendrimer such as 4(HP3T)-benzene and investigated current-voltage characteristics the OTFT devices with the condition of low light intensity. We observed the increase of the source-drain current under irradiation of light and the variation of the source-drain current with varying the energy of incident light. Using the current-voltage characteristics with light, we obtained photo-responsivity of devices. The photo-responsivity of our devices was relatively higher than that in previous reports.
