Mysterious flowers

This photograph shows mysterious flowers in their glory in darkness taken with a STEM (Scanning Transmission Electron Microscope). Flower petals are polycrystalline silicon particles grown in amorphous silicon dioxide (SiO₂). Using the FIB (Focused Ion Beam system) micro sampling method, small fragment with the size of 5 m x 5 m x 10 m had been picked up from a semiconductor device.
The mysterious flowers were contained in the fragment.
The fragment was finally trimmed to the thickness of about 1 mm, but still thicker for conventional TEM (Transmission Electron Microscope) observation. STEM capability of observing thicker specimen enables to see objects with their original 3-dimensional shape kept.
