Nanopore Formation 1

M.-Y. Wu
The movie shows the formation and shrinkage of a nanopore in a membrane composed of three 20 nm thick layers of SiO2 / SiN / SiO2. The nanopore is formed by a focused electron beam with an energy of 300 keV and a current density of 109 e/nm2s and it can be closed by a less focused electron beam ( 5*107 e/nm2s).
