The Leibniz-Institut für Kristallzüchtung (IKZ) is a unique research institution in Europe. Our mission is to explore the scientific and technological fundamentals of crystal growth, from basic research to pre-industrial development. Our materials are of fundamental importance for modern applications in micro-, opto- and power electronics, in photovoltaics, in optics, as well as in laser and sensor technology. All these applications require crystalline materials with high perfection and specific chemical and physical properties. Furthermore, we provide scientific services for research institutions and industry. This includes, in particular, the growth of specific crystals for research purposes, the characterization of crystalline materials or industry-oriented technology development.
