Carbon‐nanotube junctions: Small 24/2009

The cover picture shows two-, three-, and four-terminal carbon-nanotube (CNT) junctions with specific shape and pre-determined chirality synthesized by using a new controllable approach. In this approach, various CNT junctions can be self-assembled from two pre-tailored graphene nanoribbons based on molecular dynamic simulations. The results of charge-transport calculations suggest that the self-assembled CNT junctions have excellent functionality for nanoelectronics. Based on state-of-the-art experimental capability, this approach, with scalability down to atomic scale and screening-free selectivity, is realizable and desirable for controlling both the chirality and shape of CNT junctions, thereby dramatically improving the effectiveness of CNT junctions.
