Andreas Danilewsky
(Kristallographie, Albert-Ludwigs-Universität Freiburg)
PD Dr. Andreas Danilewsky studied Mineralogy and Crystal Chemistry
in Stuttgart. He finished his PhD 1991 at the Crystallographic Institute,
Freiburg about “Growth Kinetics and Dopant Incorporation in Semiconductor Crystals”, with space experiments playing an important role.
Since 1991 at the Crystallography in Freiburg, his research and teaching is all around the growth and characterisation of single crystals.

Shooting the laboratory into space offers unique experimental conditions: Gravity is
one of the parameters which influences fluid flows in melts for crystal growth. Convection strongly effects the quality and physical
properties of crystals. Reducing the gravity
allows a deeper insight into growth and
transport mechanisms and the verification
of numerical modelling. Some highlights
from numerous microgravity campaigns
will be reported by example of Si, Ge and
GaAs. Such semiconductors are not only of
high industrial interest, but also well suited
as model systems for basic research.
