Nanostructure machining by AFM probe combined with continuous laser
To obtain the nanostructure with stable morphology and a smallest possible size
a nanostructure machining system is established by an Atomic Force Microscopic(AFM) probe combined with a continuous laser. With this method
the study focuses on the near-field enhancement theoretical analysis and simulation when the continuous laser irradiates the AFM probe and the machining performance of this system. Firstly
based on the mechanism of surface plasmon(SP)
the Factor of Enhancement Field(FEF)
temperature field and the thermal expansion on the probe tip are researched. A nanostructure machining system is set up based on the optical fiber probe to guide the laser to irradiate on the AFM probe. At last
the polyethylene(PE) is chosen as a sample to do the experiment. Experimental results indicate that the size of the processed nanodot is about 200 nm and that of the nanowire is about 30-40 nm. This method shows the proposed probe has simple-structure and inexpensive-cost and could achieve nanostructure machining.
