Cu‐doped ZnO nanowires exhibiting high sensitivity to both UV and visible light are prepared by a vapor–liquid–solid method. The nanowires are highly resistive in the dark but exhibit several orders of magnitude enhancement in photoconductivity under UV and white‐light irradiation because of an avalanche‐type photocarrier multiplication effect, paving the way for their use in nanoscale photodetection applications.
