We have shown that the diffusion asymmetry influences the diffusion kinetics and interface morphology on the nanoscale independently of the sample structure, the chemical properties and diffusion mechanism.
Interface shift kinetics may be anomalous more often than expected. We have shown that in solid state reactions, reaction layers form and start to grow highly non-stoichiometrically and an initially existing stoichiometric compound layer may dissolve then re-form non-stoichiometrically. We have also shown that an initially diffused interface may sharpen even in completely miscible systems.
A variety of different UHV-based techniques has been used to prove the above theoretical findings in different systems.
