| Popis: | We investigated the electrical transport response of single-walled carbon nanotube (SWNT) arrays exposed to ultraviolet (UV) and ozone (O 3 ). Pure UV irradiation induced an increase in resistance due to molecular photodesorption on the nanotubes. The effect of the O 3 treatment on the resistance of SWNT arrays depended on the degree of O 3 due to different dominant mechanisms, including the transduction of molecular adsorption and O 3 doping on nanotubes as well as the creation of defects. The results suggest that the detailed control of UV/O 3 exposure could be useful in manipulating electrical devices using SWNT arrays. |
