Abstract： |
The invention is a negative light control conductance device based on macro-length single- or double-walled carbon nanotube bunches, relates to a photoelectronics device. The device consists of a single- or double-walled carbon nanotube filament bunch and to metal electrodes. Each end of the single- or double-walled carbon nanotube is connected to an electrode and sealed in a fused quartz cover. The electrodes first connect the external power source while working, and then a ray irradiates directly on the center of the nanotube filament through the fused quartz cover. The experiment shows that total conductance of the device varies by the irradiating ray intensity. The total conductance decreases while the intensity increases and increases while opposite. But the varying rate is smaller or equal to zero in spite of the intensity. The invention is of simple structure, easy process. The wave length of the ray has respondence ranged between 405 nanometer up to 1064 nanometer, and the response time is less than 1 second. |
