Fabrication of Nano-Gap Electrode using Gold Nano-Rod Growth on Substrate

Nanogap electrodes are necessary to realize nanotechnology devices such as single molecular transistor and molecular sensors. However, there is no efficient way to fabricate nanogap electrodes. Therefore we suggest new fabrication process using gold nanorod growth on substrate. In this way, when two gold nanorods grow and contact, uniform nanogap will be made because surfactant layer is surrounded by two gold nanorods. In addition, mass production can be realized by chemical fabrication process.
