STM PICTURES
OF MERCURY AND GRAPHITE
STM PICTURES
OF MERCURY AND GRAPHITE1. These are pictures of graphite. This is a three dimensional picture of a graphite surface with no defects.
2. This is a rarely seen two dimensional picture of graphite which shows honey comb structure of the carbon atoms in a graphite layer.
3. This image is of a graphite dislocation line. One can
discern the individual carbon atoms in this picture (the round patches
in the picture).
4. This is a two dimensional picture of a graphite (blue) and
mercury (orange-red) boundary. The "layering" of the liquid mercury
is seen if one looks at the columns of atoms from the boundary to the left
edge. It has been found that liquids form a layered structure next
to a boundary and when confined between two walls.
5. This is the same boundary seen in the picture above in three dimensions. Again one can clearly see the liquid mercury layered structure from the boundary to the right side of the picture.
6. This STM picture details mercury clusters on a graphite substrate. On the right one can clearly distinguish a two atom mercury cluster and a multiple atom cluster to the left.
7. The next two images are of a graphite (blue) and mercury (orange-red) boundary. In the picture on the left one can see a cerated boundary. The triangles are mercury accumulations along graphite triangular dislocations. The picture on the right is the same boundary after six scans on the STM. It is interesting that the boundary has smoothened out.
8. This a three dimensional plot of the mercury accumulation along
graphite triangular dislocation seen in the left picture of number seven.
