摘要：

We described a new structure photodetector, which is constructed by p-n heterojunction nanowire arrays of PANT (polyaniline)/CdS. The nanowire arrays exhibit excellent rectifying features and a diode nature and show a sensitive spectral response to blue light under 420 nm. The rectification ratio plots of different illumination intensities show straight line behavior, implying that the quantitative detection of illumination intensity can be achieved. The p-n heterojunction nanowire array is a great candidate for applications in high-sensitivity and high-speed blue light photodetectors.
