Black and white chocolate

These structures are defective capacitors of a Silicon chip. Polysilicon top plates present different gray levels : This is an illustration of Passive Voltage Contrast, the polysilicon top plates are charged up by the primary e-beam and this charge amount is modulated by different capacitor leakage levels.

Cretaceous sedimentary rocks

Cretaceous sedimentary rocks which occur on Snow Hill Island Antarctica, include spectacular mounds dominated by fossil bivalves. In amongst the bivalves are complex carbonate mineral cements, interpreted to have formed as a result of methane seeping through the sediments on the Cretaceous sea floor. The carbonate cements are complex but this QEMSCAN fieldscan image allows us to map the texture of polished thin sections of these spectacular rocks. Image size is 11mm square and mapped at 5 microns x-ray resolution. Image courtesy of Dr Duncan Pirrie and Dr Gavyn Rollinson, CSM,UOE,UK.

Self Assembly of Polystyrene Nanospheres

Self assembly of 500 nm polystyrene nanospheres onto optical photoresist. The nanospheres acts like microlenses, exposing the resist and patterning it with a dot structure. After metalisation (in this case sputtered permalloy) the following lift-off leaves the metal structure on the upper pert of the microphoto. In the lower part the original array of self-assembled nanospheres used as microlenses.
