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.

By two-dimensional scanning of the probe on the surface, a high resolution microscopic image is produced. Scanning Probe Microscopy (SPM), especially 2010-10-24 · This is the advantage of AFM over STM. • Resolution of STM is higher than AFM. STM gives true atomic resolution. • An AFM cannot scan images as fast as a STM, requiring several minutes for a typical scan, while a STM is capable of scanning at near real-time, although at relatively low quality.

STM used for direct determination of images of surface, with atomic resolution. an image. There are two forms of SPM: Scanning Tunneling.

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.
