Spring flower bloom

SEM image of a SiOCH thin film on silicon substrate after a nanocompression test. The mechancial testing was coupled with electric measurements thanks to a potential difference applied between the substrate and the boron-doped diamond tip. The leakage current throught the dielectric material could then be measured during the mechanical damaging of the film that gave birth to this pretty spring flower.
