Summary:High‐performance optoelectronic devices based on cup‐stacked carbon nanotubes are realized. Based on a Schottky barrier model, rectifying behaviors and high photo­response are observed by using growth catalysts as nanoscale electronic contacts. Similar performances are also obtained and furthermore tuned by using the nanotube's defective surface as effective decoration sites, transforming nanotube resistors into Schottky diodes.
