title: Mirror-image photoswitching of individual single-walled carbon nanotube transistors coated with titanium dioxide.
abstract: Dotting the i's: Stimuli-responsive optoelectronic devices are formed from the title transistors functionalized with photoactive quantum dots. The p-type semiconducting tubes show a fast current decrease under UV irradiation and reversibility when the UV irradiation is switched off. In contrast, ambipolar tubes show mirror-image photoswitching effects when negative and positive gate bias voltages are applied.
