These include scanning near-field to scanning microwave microscopy (SMM), scanning capacitance microscopy (SCM), scanning spreading resistance microscopy (SSRM), electrostatic force microscopy (EFM), current-sensing (or conductive) AFM The Atomic Force Microscope (AFM) a.k.a. Scanning Force Microscope (SFM) or Scanning Probe Microscope (SPM), has been around for almost 15 years. The microscope was an offshoot of the Scanning Tunneling Microscope (STM) and designed to measure the topography of a nonconductive sample. The AFM has undergone several enhancements over the years, allowing it to measure the local resistivity, temperature, elasticity, tribology, as well as allowing studies beyond the limitations of conventional STM - is the tunnelling current between a metallic tip and a conducting substrate which are in very close proximity but not actually in physical contact.

The last metal atom of the tip (tip base) is shown in sand color, the probe particle in cyan, and the molecular layer (sample, in the exam-ple a herringbone PTCDA layer) in gray (carbon atoms) and red (oxygen atoms). This webinar will explain the basics of STM and review ambient and liquid STM experiments using Park NX series AFM systems. More recent advances in our powerful data analysis software, SmartScan, will be introduced, including PinPoint mechanical mode Nanolithography functions. Slide 1.

STM technique to investigate the electrically non- conductive  Jun 30, 2010 AFM, atomic force microscope; BEEM, ballistic electron emission high resolution AFM is comparable in resolution to STM and TEM. The experimental setup provides a combined scanning tunneling and atomic force microscope. (STM/AFM) that is entirely incorporated in an in-situ ultrahigh  Atomic force microscopy (AFM)?

Both AFM & STM are surface microscopy techniques that can determine the topology of a surface & both widely used across chemical & nanoscience fields.

Brief History of AFM Atomic force microscopy (AFM) was developed when people tried to extend STM technique to investigate the electrically non-conductive materials, like proteins. In 1986, Binnig and Quate demonstrated for the first time the ideas of AFM, which used an ultra-small probe tip at the end of a cantilever (Phys. Rev. Letters, STM AFM The size of the tip and the resolution IT: exponential dependence of distance tip-sample, closest atom of tip interacts with surface atomic resolution is achieved Several atoms of the tip interact with the sample surface, every atom of the tip „sees“ a shifted lattice with respect to the lattice seen by the neighbor atom The STM was the first instrument to generate real-space images of surfaces with so-called "atomic resolution." This would later be known as atomic lattice resolution. The operation of STM and Conductive AFM is identical except that one uses a sharpened and conducting wire/tip in STM instead of a conductive AFM cantilever.

The AFM has the advantage of imaging almost any type of surface, including polymers, ceramics, composites, glass, and biological samples.

Scanning Probe Microscopy (SPM), especially Nanometer Size Pattern Formation by STM/AFM The pattern formation procedure by STM nano-oxidation process is shown in Figure 1. After deposition of the thin Ti layer (3 nm thick) at the low pressure of 10-7 Torr, the sample was set in an air ambient STM. The Ti surface was biased positively to the Pt STM tip.
