Product Details

Scanning Thermal Microscopy (SThM) is an advanced SPM mode intended for simultaneous obtaining nanoscale thermal and topography images. A SThM kit is able to visualize temperature and thermal conductivity distribution at the sample surface. The SThM system hardware includes electronic controller, software, and probes.

SThM mode of operation with an AFM requires a specialized probe with a resistor built into the cantilever. The SThM module allows one to monitor the resistance changes correlated with the temperature at the end of the probe. So the system is able to monitor relative changes of sample temperature and thermal conductivity.Our thermal probes provide better than 100 nm lateral resolution for both topography and thermal images.

The specialized SThM cantilever, made of SiO2 with a thin metal layer, is deposited on the probe in such a way that the highest resistance portion of the layer is concentrated near the tip apex.

Sample: Optical Fiber in Epoxy.
Scan size: 6 x 6 um.
