(a) TEM image (mass thickness contrast) of a FIB-prepared cross section showing a deposited porous magnesium silicate layer on a silicon wafer. The layer has a variable thickness and a very high porosity. The thickness of the prepared TEM sample in beam direction is about 100 nm. The metal coating is protecting the surface during the FIB sample preparation. (b) and (c) Magnified view of the porous and foam-like structure of the film. Brighter areas represent less solid material in the beam direction. Areas with pore diameters over 100 nm are scarce, and most pores measure less than 20 nm. -- Heriot-Watt University
