The single nanodevice-based ultrathin N-doped
helical carbon nanotube (N-doped HCNT) was fabricated for
systematical examinations of photoconductivity. A 515 nm
focused beam of about 300 !m in diameter was applied for
irradiation. The study showed that the N-doped HCNT has
high generation of photocarriers and high bimolecular
recombination rate. The photoluminescence (PL) properties
of the N-doped HCNTs were examined systematically. The
results indicated that the photoresponse can be improved
further by selecting an appropriate wavelength excitation.
