Scanning thermal microscopy

This is an example of a scanning thermal measurement performed with a FlexAFM scan head equipped with a VertiSense temperature sensing cantilever from AppNano.

3D overlay of temperature over topography

Temperature shown as color overlay on the 3D topography.

Data processing: Gwyddion
Image size: 25 µm
Temperature range: 15 degrees

Sample structure

The sample consists of two high dose implanted Si tongues with a low dose connection in between. When applying a potential between the tongues, the temperature increase is highest in the connection.

VertiSense Imaging Amplifier (AppNano)

The amplifier is connected to a user input of the Nanosurf AFM controller (Easyscan 2 or C3000) via a BNC cable.
