Subproject 8: Ultraslow Li Transport on the nanometer scale

Leitung:Schmidt, Heitjans
Bild Subproject 8: Ultraslow Li Transport on the nanometer scale

The experiments will be done by macroscopic tracer methods (secondary ion mass spectrometry and neutron reflectometry) in combination with isotope heterostructures. The possibility of neutron reflectometry to detect diffusion length of 1 nm allows the direct comparison to microscopic methods (Spin-Alignment-Echo-NMR) on the same length scale. The work should also contribute to a better understanding of atomic transport on different length and time scales using different analytical methods. The experiments will be complemented by conductivity measurements.
