the scanning tunneling microscope ~STM! and atomic force microscope ~AFM! to pattern other orientations of silicon. The mechanism for this type of lithography is presumed to be that the intense field from the tip desorbs the hydrogen and increases the oxidation rate on the exposed silicon.

Gone are the days when sub-nanometer molecular resolution was the province of only STM. Since STM and AFM operate in near field regime, lithography far less affected by diffraction and proximity effect which arise with optical or e-beam lithography. Local anodisation with an AFM is a versatile method to make nanoscale quantum devices [1,2]. Here we present results based on the controlled oxidation of metallic ultra-thin films. A100 AFM- A100 PLUS AFM A100 AFM is a versatile atomic force microscope suited to a wide variety of applications including bioscience, surface science, semiconductor technology, magnetic media, polymer science, optics, chemistry and medicine. The close loop flexure scanning stage guarantees absolute positioning and high planarity.

If these actions can be performed in a controlled way widespread possibilities would arise: information storage devices, nanometer patterning technique, manipulations of big molecules and individual atoms, building of small devices.The most straightforward way to machine a surface by STM is by oxidation experiments was replaced by the atomic force microscope (AFM) as the main instrument to perform o-SPL [31, 33–35].

Applying a negative potential to the AFM needle tip, while the silicon substrate is held grounded causes a negative electric field to be generated in the region. When the ambient is highly humid, a water meniscus forms between the AFM needle tip and the silicon substrate, shown in Figure 2.16. Atomic force microscopy (AFM) stands apart from other methods of microscopy, which use light or an electron beam to obtain an image. AFM, also called scanning probe microscopy, scans the surface with a probe, or a flexible cantilever with a pointed tip, making very small, precise movements.
