What is Tip Cleaning and Sharpening Processes for Noncontact Atomic Force Microscope in Ultrahigh Vacuum about?
Tip cleaning and sharpening processes for noncontact atomic force microscope AFM operated in ultrahigh vacuum Ž . Ž . UHV were carried out and evaluated by a scanning Auger microscope SAM with a field emission electron gun and a noncontact AFM in UHV combined with a scanning tunneling microscope and a field emission microscope. The cantilever used in this study was piezoresistive, which can be heated by passing a current through the resistive legs of the cantilever. As a pretreatment, the tip was irradiated with ultraviolet light in oxygen to remove carbon contaminants. It was heated at about 7508C to form a clean oxide layer in oxygen of 5 = 10 y5 Torr in an SAM chamber. The desorption of the layer can make a remained tip apex sharper by heating under electron beam irradiation. A thermally oxidized layer was also eliminated by HF etching to sharpen the tip apex. The procedures are useful to obtain a well-defined Si tip suitable for a noncontact AFM.
