In Situ Growth of Nanowires and Fabrication of Nanogap Electrode Pairs by Selective Chemical Deposition with the Assistance of an External Magnetic Field.
We have successfully had nanowires in situ grow on the tip of an electrode by selective chemical deposition with the assistance of an external magnetic field. The nanowires are a few microns in length and just a few hundred nanometers in diameter. At the same time, the lateral extent of electrode was not increased obviously. This method combined the lithography technique, self-assembly monolayer (SAM), chemical deposition and the external magnetic field to get nanowires in situ grow on the tip of an electrode. So we can control the growth direction of nanowires along the specified direction at desired locations. Finally, we have fabricated the nanogap electrode pairs by means of the properties of nanowires with grown on the tip of elelctrode in magnetic field.
