SEM images of the isles that were milled using FIB. Images show a cross section of one isle (scale bar representing 10 µm), b higher magnification of image a showing the lines on the edge (scale bar representing 10 µm), and c cross section of another isle showing the porosity of the isle–SPE interface (scale bar representing 20 µm)
