STM image of FeSi₂ showing the heavily stepped nature of the surface. The smallest step corresponds to 1 atomic layer

STM image of single molecule of a bi-porphyrin.

Combined STM (topography) and photon emission (colour) image of a mixture of gold particles and SiC particles showing that the gold particles emit light whilst the carbide particles do not.

Perspective STM image of a Titanium Silicide crystal showing the atomic structure of the faces.

Scanning Electron Microscope writing on PMMA plastic of a passage from Encyclopaedia Britannica. Each letter is 250nm tall. If one letter is considered to be equivalent to 8 bits then the storage density achieved here is around 1000 Gbit in-2. Or you would be able to write the whole Oxford poetry dictionary on the area of one letter on this page.

STM image and photon map from SiC particles embedded in a Si (111) 7x7 surface. Light emission at step edges and in the 7x7 terraces is observed whereas the SiC does not emit.
