One Volt Organic Transistor

Solution-based anodization of titanium can deliver high-capacitance, pinhole-free TiO2 films where the film thickness is controlled by the anodization voltage. In conjunction with the organic semiconductor pentacene, such films can be used to manufacture transistors that operate at less than 1 V (see Figure). Low-cost, disposable devices with low available voltages could take advantage of these flexible organic transistors.
