A high-performance fully nanostructured individual CdSe nanotube photodetector with enhanced responsivity and photoconductive gain

Single-crystalline CdSe nanotubes with a perfect hollow tubular architecture and higher surface-to-volume ratio were synthesized via a simplified one-step ambient pressure physical vapor deposition process and utilized to fabricate an individual CdSe nanotube photodetector with enhanced responsivity and photoconductive gain.
