Fabrication of Nano Logic Gates Based on ZnO Nanowires
With the rapid expansion of nanotechnology, assembling nano-materials and to create electrical/mechanical devices at micro and nano scales has become an increasingly important research area. An “OR” logical gate at nano-scale has been constructed with ZnO nanowires (NWs) via a mechanical nano-manipulator which placing inside the vacuum chamber of a scanning electron microscope (SEM). By means of the electrostatic interactions and the characteristics of ZnO NWs, the on/off effect between probe tip and NW can be controlled by controlling the voltage between them. Experimental results show that the fabrication of nano logic gates based on ZnO NWs is possible.
