... manner, thus exposing a new surface to be analyzed. By sequentially sputtering and taking AES data, a compositional depth profile may be generated that shows the AES signal for selected elements as a function of sputter time (depth). Exact sputter depths are often difficult to obtain, because exact...

... conditions that optimize the energy resolution of the data. Compositional depth profiling is possible in AES with the aid of an inert gas sputter ion beam. The ion beam is used to slowly remove material in a controlled manner, thus exposing a new surface to be analyzed. By sequentially sputtering...
