Carbon nanotube array have a potential to be efficient spectrum detection material due to their unique electronic properties. A photodetector based on carbon nanotube is developed by fabricating the electrodes with photolithography techniques and then synthesizing the carbon nanotube array that contact with the electrodes with chemical vapor deposition oriented growing techniques. The structure of the photodetector based on carbon nanotube is characterized with scanning electron microscope pictures and the electronic behavior of photodetector based on carbon nanotube array is investigated with I-V curves. The photocurrent of the developed device has been measured under the different light illumination. Photodetector based on carbon nanotube array has different current output corresponding to different light illumination, which can be used to detect the incident light and verify the functionality of the photodetector based on carbon nanotube array, giving a new idea for the fabrication of devices based on carbon nanotube.
