Research field : crystal growth
Peter Gille’s crystal growth group at the LMU Department of Earth and Environmental Sciences, Crystallography section, is interested in all kinds of crystal growth activities with the main focus on intermetallic phases. The group of intermetallic phases summarizes a huge number of compounds formed by two, three, or even more individual metals. Since there are more than 70 metals among the elements of the periodic table, the playground of intermetallic phases is almost infinite.
Intermetallics that we are interested in can be used for heterogeneous catalysis, for thermoelectric applications and for basic research in different fields of solid-state research.
The easiest way to study the intrinsic properties of an intermetallic phase is to measure the anisotropic properties of single crystals. That’s why, we try to find optimum conditions for single crystal growth of intermetallic phases. Since most of the metallic elements easily oxidize, synthesis and crystal growth have to avoid any contact to oxygen and, consequently, we have to use ultrapure conditions in fully metal-sealed apparatuses for crystal growth.
Crystal growth may be regarded as Applied Thermodynamics. Binary and ternary phase diagrams are basic as to understand crystal growth conditions. Crystal growth of intermetallic phases very often occurs under off-stoichiometric conditions, i.e. from peritectic systems using one of the components as native solvent. The method of choice is the Czochralski technique that we use to grow cm-sized single crystals of a variety of intermetallic compounds from high-temperature solutions. We have established a fruitful co-operation with colleagues in various countries studying the physical and chemical properties of these crystals
