This sample consists of discrete gold particles on a featureless carbon
support film. The particles range from 2 nm to 9 nm in size; the larger
particles are most suitable for high resolution tests. The larger particles
may be "necked" together or otherwise agglomerated.
The resolution of a high resolution transmission electron microscope can
be evaluated by lattice imaging of the gold, which exhibits particularly
strong diffraction in the larger particles.
