摘要：

The spatial resolution of photocurrent measurements on carbon nanostructures has reached 20 nm, as demonstrated by Hartschuh and co-workers for individual carbon nanotubes in this issue of ACS Nano. In this Perspective, we provide a brief overview of the applications of scanning photocurrent microscopy to various one- and two-dimensional nanostructures and highlight the importance of the optical antenna concept for future studies of the optoelectronic properties of hybrid nanostructures.
