摘要：

Pentacene organic thin-film transistors (OTFTs) with a high-k HfLaO dielectric were integrated onto flexible polyimide substrates. The pentacene OTFTs exhibited good performance, such as a low subthreshold swing of 0.13 V/decade and a threshold voltage of -1.25 V. The field-effect mobility was 0.13 cm(2)/V . s at an operating voltage as low as only 2.5 V. These characteristics are attractive for high-switching-speed and low-power applications.
