The Didodecyl-Benzene Molecule
Model of the self-assembled Didodecyl-benzene molecule. |

Raw Zoom
Raw zoom showing 3 Didodecyl-benzene molecules. |

|
Average Image
The average image exhibits the finer details of the inner molecular structure.
|
 |
|
Standard Deviation
The Standard Deviation image showing the lowest values on the right side of the
benzene ring reflects the least dynamic part of the molecule and reveals how it
is attached to the graphite substrate. |
 |
|
Cross Correlation
Cross correlation between Raw Image and Average Image.
This image is used by the algorithm to find regions with good matches to the
row zoom image. By adding all these regions the average image is obtained. The
high quality is assured by sub-pixel alignment. |
 |
|
Fourier Transform
The cross correlation image is found by use of Fast Fourier Transformations. |
 |
|
Versatile Technique
The Correlation Averaging technique can also be applied for robust step height
calibration and uniformity evaluation. The method works on profiles as well as
images. |
