A facile solution‐phase reaction has been developed to fabricate carbon nanotube/CdS core–shell nanowires (see Figure). The thickness of the CdS sheath can be controlled by varying the concentration of the precursors. The obtained heterostructures demonstrate an enhanced surface photovoltage response, which is associated with the efficient photoinduced charge transfer from the CdS shell to the carbon nanotube core.
