Abstract

original image

Organic single-crystalline nanoribbons are fabricated through an in situ patterning technique to yield various architectures. Organic field-effect transistors based on such patterned nanoribbons (see figure) are shown to exhibit low threshold voltages and high carrier mobilities. This in situ patterning technique overcomes the general disadvantages of the handpicking process for the fabrication of organic single-crystal devices and opens up a new route for the fabrication of architectures and devices using nanocrystals.
