Max Planck Institute for Chemical Physics of Solids

Max Planck Institute for Chemical Physics of Solids

The Max Planck Institute for Chemical Physics of Solids is dedicated to the discovery of new materials with unusual properties. To this end, researchers must have a fundamental understanding of the interrelations between the atomic structure, chemical bonding, electron states and the properties of a compound. The key research focus of the Institute is compounds of different metals. Chemists and physicists as well as experimental and theoretical scientists use state-of-the-art instruments and methods to investigate how the chemical composition, configuration of atoms and external forces affect the behaviour of electrons. It is these that are responsible for the magnetic, electronic and chemical properties of the compounds, and thus for their potential use as materials.

It is frequently only the development of new materials that makes technological advances possible, whether in the areas of energy supply or information technology. With the Heusler compounds, Claudia Felser, Director at the Max Planck Institute for Chemical Physics of Solids in Dresden, uncovered a rich source of materials that offer promising properties for a variety of applications.

Electric cables that routinely conduct electricity without loss – physicists have been motivated by this idea ever since superconductivity was discovered 100 years ago.

Electricity from Hot Air

MPR 1 /2011 Materials & Technology

Even the most efficient motor generates more heat than propulsion. However, thermoelectric generators could convert some of this unused energy into electricity. Scientists are currently searching for suitable materials.

They are called otoconia – tiny crystals in the inner ear that help us maintain our balance. A good reason to take a closer look at these particles.

The quantum sound of metals

2018 Hassinger, Elena

Chemistry Material Sciences Particle Physics Plasma Physics Quantum Physics Solid State Research

Every musical instrument has its own sound with a frequency spectrum that is determined by the shape of the instrument. In analogy to that, every metal has its characteristic frequency spectrum reflecting the properties of its electrons. Our investigation of the quantum sound of electrons in the metal PdRhO2 shows that electrons move quickly in the crystallographic planes whereas they hardly move perpendicular to the planes. The quantum music sounds slightly differently than expected and will help understand the particular hydrodynamic transport properties of electrons in these metals.

Covalence and ionicity in compounds of MgAgAs-type: from concepts to structure prediction

2017 Wagner, Frank R.; Bende, David; Grin, Yuri

Chemistry Material Sciences Particle Physics Plasma Physics Quantum Physics Solid State Research

Analysis of chemical bonding in compounds of the MgAgAs type of structure by bonding indicators in position space resulted in a generalization of the 8­–N rule for bonds of variable polarity. Position-space indicators enable quantification of ionicity and covalence, which was successfully used to explain the different site preference in main-group and transition-metal compounds of the MgAgAs type. On this basis, it was possible to propose promising candidates for new compounds with the MgAgAs structure type, which was subsequently verified for the majority of compounds by laboratory synthesis.

Topological Weyl semimetals

2016 Yan, Binghai; Felser, Claudia

Chemistry Quantum Physics Solid State Research

In recent years, theoretical physicists discovered that the topology of a material can lead to interesting new quantum properties. This simple concept can be applied to the electronic structure of semiconducting materials in which relativistic effects are important. In 2015, several materials like NbP, NbAs, TaP, TaAs, und MoTe2 have been suggested by theoreticians as promissing, so-called Weyl semimetals, and have been physically characterized just a bit later. The special feature is that Weyl fermions, which occur in these materials as quasiparticles, exist in two chiralities.

Hunting for the electrical properties of topological insulators

2015 Höfer, Katharina; Becker, Christoph; Rata, Diana; Swanson, Jesse; Thalmeier, Peter; Tjeng, Liu Hao

Chemistry Solid State Research

Topological insulators form a novel state of matter that open up new opportunities to create unique quantum particles. Many exciting experiments have been proposed by theory, but still await their experimental verification, not to mention their implementation into applications. The main obstacle is the extrinsic conductivity associated with the unavoidable presence of defects in their bulk, as well as impurities on their surfaces. For Bi2Te3 films it is possible to obtain the desired quality by carrying out the preparation and characterization entirely under ultra-high vacuum conditions.

From palladium to noble metal-free hydrogenation catalysts – intermetallic compounds in catalysis

2014 Armbrüster, Marc; Kovnir, Kyrill; Friedrich, Matthias; Grin, Yuri

Chemistry Material Sciences Solid State Research

A knowledge-based concept has proven as efficient strategy for the development of innovative catalysts. Understanding of the crystal structure and the atomic interactions within intermetallic compounds allows for selection of suitable intermetallic compounds as effective hydrogenation catalysts. In contrast to the widely applied trial-and-error approach, the knowledge-based approach is an advantageous alternative, demonstrating the application potential of intermetallic compounds in heterogeneous catalysis.
