For imaging in Non-contact Mode or TappingMode, a frequency synthesizer creates the cantilever oscillation via a piezo embedded in the probe mount. Other forms of SPM There are multiple other forms of scanning probe microscopy (SPM), all of which are modifications of the principles of AFM or Scanning Tunneling Microscopy (STM) :

The probe is a metal needle. Detector signal is the tunneling current between the tip and sample when an electrical bias, V, is applied. In feedback mode, output signal usually adjusts the Z position of the scanner to maintain a tunneling current setpoint. STM is the highest resolution AFM. The images below show constant-height STM images, but the full application note demonstrates similar resolution in constant current STM mode.

Gone are the days when sub-nanometer molecular resolution was the province of only STM. 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, 1986, Vol. 56, p 930). In 1987, Wickramsinghe et al. developed an AFM setup with a vibrating (AFM): strumentazione •Ceramico Piezoelettrico: posizionamento fine •Movimento in x, y e z da pochi angstrom fino a 100 micron Lo scanner DATA SET •Altezza dello scanner in z: costant force (AFM) o constant current (STM) mode •Deflessioni del cantilever o della corrente i tunneling: constant height mode (AFM, STM) By comparing topographic images of the pn junction acquired in contact AFM mode with the STM images, large variations of STM topography and normal force across the junction could be observed.

In general, possible imaging modes are divided into static (also called Contact)  STM. AFM. PEEM. Topography.

STM AFM mode, the SEM electron beam is focused on the edge of the cantilever such that any deflection of the cantilever causes a change in the number of electrons scattered off the 2018-07-23 · After seeing the resolution of those images, Roger suggested to me that it might be possible to see the CoOEP lattice using tapping mode AFM (amplitude-modulated AC mode) instead of STM, owing to Cypher’s stability .
