T.E.M. TECHNIQUES FOR THE ATOMIC LEVEL CHARACTERISATION OF NANOMETRE SCALE MULTILAYERSW.M. STOBBS

The transmission electron microscope techniques which can be applied to the atomic level characterisation of interfaces, heterostructures and multilayer systems are described. Many of the approaches required are indirect. This is partially because of the need to differentiate the effects of a displacement from those of a composition change and partially because of the general problem of ensuring that a given structural model provides a unique fit between a set of simulated images and those obtained experimentally.
