Thanks a bundle! A strong photoresponse for macroscopic bundles containing thousands of aligned carbon nanotubes (suspended between two electrodes, see figure) upon illumination is observed at wavelengths ranging from the visible to the far‐infrared. At a relatively small applied bias, the current flow in the nanotube bundles changes linearly with incident light over a wide range of laser power, although the current response in the different types of nanotubes (multi‐walled, single‐walled, and double‐walled) varies in magnitude and direction.
