Nano-Heterojunction Self-Assembly

摘要

Nanoscale materials can now be synthesized by a wide range of methods, including self-assembly techniques. The junction regions between dissimilar materials often have unusual and desirable properties. Zhang et al. (p. 340) were able to extend the self-assembly toolbox to make heterojunctions of semiconducting nanotubular segments. The conjoined segments could transport electrical charge and also increase the lifetime of photogenerated charge carriers.
