The VT SPM Lab system ensures high stability SPM work in a stand-alone UHV system while various adaptations are available to interf Low energy exposure is the key feature of STM/AFM-based lithography. After emitted at low energy (few eV), electrons lose energy due to inelastic scattering with resist molecules as well as gain energy from the high electric field. A scanning tunneling microscope (STM) is a type of microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986.
AFM lithography, without using potential difference, can be produced applying metal cantilevers with diamond
This third generation of the LT STM enables our customers to carry out the most advanced low temperature STM, spectroscopy and QPlus® AFM experiments. And like its previous iterations, the ease-of-use, stability and proven reliability in the LT STM ensure a high productivity, workhorse microscope. The scanning tunneling microscope (STM) and atomic force microscope (AFM) provide, not only ‘eyes’ but also ‘hands’ to investigate and modify nano-objects.

oxidation experiments was replaced by the atomic force microscope (AFM) as the main instrument to perform o-SPL [31, 33–35]. In fact, the replacement of the STM by the AFM has been a common feature in the development of robust and reliable probe-based patterning methods. The AFM is more suitable for lithography experiments because the feedback

(1) It has longer tapered length STM tip and smaller half cone angle to include AFM-based lithography such as tip-catalyzed surface reactions,41 dip-pen nanolithography,42 and STM-based lithography such as tip-assisted electrochemical etching and field-induced desorption.43 2.4.3Atomic Force Microscope Lithography 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. Scanning probe lithography (SPL) describes a set of nanolithographic methods to pattern material on the nanoscale using scanning probes. It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm.
