Materials science, and more precisely crystal growth, is a full scientific branch gathering together physics, chemistry, crystallography, metallurgy, engineering and computing, in the aim of producing the wanted material with the desired properties. The complexity and the richness of novel materials, as well as the oncoming demands in terms of energy saving, efficiency, improving quality of life, challenge every day physicists and chemists with the need of new and better crystalline materials, both for fundamental research and applications.
The Laboratory for Materials Processing and Crystal Growth of the Department of Quantum Matter Physics (DQMP) of the University of Geneva belongs to the Optics and Crystal Growth Group lead by Prof. Dirk van der Marel. The main mission of the LCG is to provide the research activity of the group, as well as that of the whole DQMP, with the crystalline and polycrystalline materials needed for experimental research in solid state physics. Moreover, a strong effort of the LNG is devoted to the search for novel materials with potential applications in novel electronics. The LNC has external (both national and international) collaborations on a variety of materials as well.
The materials processed, grown and investigated at the LNC include:
- High-Temperature Superconducting Cuprates
- Fe-based Superconducting Chalcogenides and Pnictides
- 2D Transition Metal Dichalcogenides
- Other layered semiconducting materials (“tetrel”-pnictides, layered halides,…)
- Transition Metal Silicides
- Correlated Transition Metal Oxides
The laboratory is equipped for the production of crystals of various and very different materials, thus allowing a large versatility in research on quantum materials: image furnaces for Travelling Solvent Floating Zone, HF induction furnaces for Czochralski growth, even in oxidizing atmosphere and from levitating melt, arc furnaces, high-T high-P cubic anvil press, high-p(O2) furnaces (100bar), two- three- and five-zone tubular furnaces, many furnaces for solid state reactions under various conditions.
The activity of the laboratory is carried out by a team of 1 staff member, 1-2 post-docs, 1 graduate student and 1 technician.
