 3D image


Imaging conditions:

  • Nanonics MultiView 400 system with a Ultrasharp probe in air 
  • 10 x 10 micron Flat Scanner, z-range: 2 micron 
  • Intermittent Contact mode imaging

In the 4.5 x 4.5 micron image, it can be clearly seen, that the polymer surface is very flat, but it consists of two distinct phases. There are islands which are 5 – 8 nm higher than the lower parts.

The same features are visible in the 1.5 x 1.5 micron image. In addition a granular structure of both the islands and the lower surface is visible in this image. This granules can have a connection to the incorporated Nickel, but it is also possible, that this granules are connected to the way the polymer film was fabricated.

The 0.55 x 0.55 micron image shows again the granular structure of both the islands and the lower surface. The granules are 20 – 50 nm in diameter and 0.5 – 2 nm high.There seems to be no difference in granularity between the islands and the lower polymer surface.

  3D image

Only Nanonics is able to produce AFM images with such a large z scan range.

 


The large 70 micron z scanning range of theNanonics 3D FlatScan Scanning System and the up to 500 micron tip length of the cantilevered optical fiber Nanonics Deep Trench AFM probe allows even larger topographic alteration to be readily monitored. 

The image was obtained with normal force feedback in the intermittant contact mode using the MultiView 400™.

Simultaneous Resistivity Image of the same region

Nanonics Thermal Probes have a thermal response time under 20us, thermal resolution under 10 millidegrees and nanometric spacial resolution.

In the Dual Wire Thermoresistive probe, two platinum wires are stretched through the nanopipette and fused together at their tips. This fused junction has a resistance that is temperature-dependent. This unique tip allows simultaneous measurement of surface topography with thermal conductivity or temperature.

4x4 micron Collection NSOM image taken during operation   Thermal Image of the same region

The collection mode NSOM image clearly reveals the V-shaped evanescent field on either side of the Quantum Well Laser. Note that areas with high light intensity are not identical with areas of high thermal intensity. This information can only be uncovered by simultaneous imaging.

These Images were produced using the The MultiView 1000™ and Nanonics Thermal Probes.

Only Nanonics Thermal Probes have a thermal response time under 20us thermal resolution under 10 millidegrees and nanometric spacial resolution.
