Studies of diffusional movement of atoms through interfaces and of the
resulting interface shift are nowadays of great interest not only from
a fundamental research point of view—search of diffusion laws valid on
the nanoscale—but they are of practical importance as well. Recent
progress in device technology allows one to directly approach
structures on the nanoscale, for which the knowledge of the
corresponding diffusion laws is indispensable. Also related to this
topic is the possible degradation of parts of electronic devices being
often due to material transport through interfaces. Accordingly, in
order to extend the lifetime of such devices a detailed picture of the
underlying diffusional processes is required.
The aim of this site is to summarize different interesting diffusional nanoscale effects discovered in the last ten years.
