Dr. Harald Reichert –
Solid-Liquid Interfaces
|
 |
Pentagonal arrangement of Pb atoms at a Si(100) surface |
|
The structure of a liquid in contact with a solid is much more complex than
the corresponding bulk structure of the liquid. Due to geometrical
(symmetry break
at the interface) and chemical (interaction of the liquid atoms/molecules
with the wall) effects, complex ordering phenomena may be induced in the
vicinity
of the wall. Additional effects such as charge transfer at the interface
may further complicate the situation.
In this project we have developed an experimental technique for the
structural investigation of deeply buried interfaces employing high
energy microbeam diffraction.
Using a dedicated instrument at the high energy
beamline ID15A at the ESRF (Grenoble), which was built and is operated
by the Department Dosch, we are
investigating the structure of various liquids in contact with a variety of
materials such as semiconductors and insulators.
Current topics
- Structure of solid-liquid Schottky contacts under the variation of substrate/liquid material, orientation of the solid and temperature
- Solidification at heterogeneous solid-liquid interfaces
- Dynamics at liquid surfaces studied by inelastic x-ray scattering
- Structure of liquids in confinement
