Scanning Probe Microscope

Temperature and Humidity Controller

Controller is attached to an environment controlled chamber to control the temperature and humidity inside the chamber.

FC Film Observation with Environmentally Controlled Temperature and Humidity

Variations in the surface shape of Nafion film due to changes in humidity were observed. In each case, microscopic features of about a few nm in height were observed, but the images show that increasing the humidity results in smoother features and more swelling.

Polymer Film

Variations in the shape of polymer film were observed using a controlled temperature and humidity environment.

Gas Spray Unit

The gas spray unit is attached to a spare port to spray small amounts of gas on the sample.

Real Time Observation of Nickel Surface Variations

The nickel surface's reaction to gas was observed continuously in real time. When the clean surface after reduction (left) started being sprayed with carbon monoxide, the change in shape was observed as carbonyl complexes were formed (right).

Sample Heating and Cooling Unit

The sample can be loaded into the unit and heated or cooled.

Observation of Cooled Plastic

Two separate phases were observed in the viscosity image

After cooling, there were almost no visible differences in viscosity.

Sample Heating Unit

The sample can be loaded into the unit and heated. The unit can even be operated in atmospheric conditions, depending on the sample.

Observation of Heated Polymer Film

The phase image (right) clearly shows the changes in sample surface physical properties as the sample is heated.

Light Irradiation Unit

This unit enables using a fiber optic light to irradiate sample surfaces. It does not include the light source or the optical fiber. It can be operated in atmospheric conditions.

Observation of Ultraviolet Light Irradiating Pentacene Thin Film on SrTiO3

The pentacene thin film was formed as a cluster of two or three 1.6 nm thick layers. When irradiated with 365 nm wavelength ultraviolet light, the cluster structure gradually started breaking apart. After 40 minutes, the thin film cluster was mostly gone. During this time, there is negligible drift and observation is possible using the same field of view.
