Multilayer thin films of various metal pairs present model systems for studying intermetallic
alloy phase formation at interfaces of these heterostructures on annealing and help to …

Self-diffusion in intrinsic single crystalline germanium was investigated between 429 and
596 C using G 70 e/G nat e isotope multilayer structures. The diffusivities were determined …

To provide insight into the effect of grain size on the precipitation behavior of γ
″strengthening superalloy Inconel 718, a gradient nanostructure with a large grain size …

Nitrides of 3 d ferromagnetic metals (Fe, Co and Ni) or transition metal nitrides (TMNs)
appearing late (Group 8–10) in the 3 d series are emerging compounds in a wide range of …

Since many years, the contribution of vacancies (V) and self-interstitials (I) to silicon (Si) self-
diffusion is a matter of debate. Native defects and their interaction among themselves and …

Li self-diffusion in Li2O-deficient LiNbO3 single crystals is investigated in the temperature
range between 423 and 773 K (150–500° C) by secondary ion mass spectrometry. A thin …

We present in-situ self-diffusion experiments in solids, which were carried out by Focussing
Neutron Reflectometry on isotope multilayers. This new approach offers the following …

The present Letter reports on self-diffusion in amorphous silicon. Experiments were done on
Si 29/Si nat heterostructures using neutron reflectometry and secondary ion mass …

We present a new method for the determination of self-diffusivities in solids and the
corresponding activation energy of diffusion using in-situ Neutron Reflectometry. In contrast …

Two-stage oxidation experiments using 16O and 18O isotopes were performed to reveal the
governing atomic transport mechanism (s) in thin (thickness< 10nm) oxide films grown …
