3. Surface Potential Measurement
•An SPM that capture the surface potential
that does not appear in the surface shape to
an image
•Measures the samplefs surface potential using the static electricity between
the probe and the sample.

4. KFM Measurement Example (1)
Electric potential difference between area oxidized by electric-field
enhancement and area naturally oxidized on metallic thin film
5. Environment Control SPM (SPA-300HV)
- Various environment control possible.
•Vacuum: up to 10-7Torr
•Program temperature -120 to +800 oC
•Gas exchange in chamber possible
- Multi-Function Compatibility
•The same multi-function measurement as atmospheric units, such as micro
viscoelasticity and friction distribution are possible in various environments.
6. SPM in liquid /Electrochemical SPM
Block diagram of Electrochemical STM
Compared to atmospheric STM, STM in solution
is covered with liquid that has ion conductivity.
The main distinction between them is the ion
current from electrochemical reaction that
flows while voltage is impressed on the probe
and the sample. Since it is necessary to conduct
SPM observation while independently controlling
the probe and the sample, the device is formed
with a four-electrode system that utilizes
a bipotentiostat.
Because the optical lever AFM operates in
environments where the detection light filters
through, it is possible to observe samples
in solution. High magnification electron microscopes
cannot be used to directly observe samples
in solution, but with SPM in liquid, high magnification/on
site observations of raw/live organism samples
and samples during reaction process in solution
are enabled.
7. Features of Schale Submerged Cell
•Because of the open structure that does
not place load on the PZT scanner, constant
PZT sensitivity can be maintained.
•
Sample/solution exchange can be made easily.
•
Since the cell is simply placed, measurement
location can be moved up to maximum of about
10mm.
