Lithium batteries that provide electric cars with power, superconductors that conduct electricity over long distances without loss, solar cells that harvest solar power – all of these examples are based on the electrical conductivity characteristics of solid materials. These are some of the phenomena which scientists investigate at the Max Planck Institute for Solid State Research. Solid state materials include metals, ceramics and even crystals of organic molecules. Just how the structures of these materials affect their electrical, mechanical and magnetic properties, is what solid state researchers seek to understand. To this end, the researchers particularly focus on solids at the nanoscale, which behave differently compared to materials in larger dimensions. In order to miniaturize electronic circuits even further or to prepare for the electronics that will follow on from the silicon era, the behaviour of these solids needs to be controlled.

Quantum World in a Cube

1/2014 Material & Technology

Nanoelectronics is at once a promise and a challenge. Within their tiny dimensions, electrons, the drivers of electronic circuits, exhibit some exotic quantum effects. Using ultrasensitive techniques, researchers in Klaus Kern’s department at the Max Planck Institute for Solid State Research in Stuttgart are studying the behavior of electrons in nanostructures.

Printable, flexible and low-cost – these are the properties that engineers hope to achieve with organic electronics. Researchers at the Max Planck Institute for Solid State Research and the Max Planck Institute for Polymer Research are investigating various materials that can be used to manufacture monitors that can be rolled up, or low-cost chips for mass-produced articles.

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

Researchers aim to revolutionize blood sample analysis with highly sensitive diagnostic chips.

A great deal of energy could be saved if turbines and combustion engines operated at higher temperatures than they currently do. Ceramic high-temperature materials make this possible. Martin Jansen, Director at the Max Planck Institute for Solid State Research in Stuttgart, has been conducting research into just such a new material for 20 years. It is now ready for the market.

Flexible organic transistors and integrated circuits with extremely small supply voltages of 0.7 V

2018 Klauk, Hagen

Chemistry Material Sciences Solid State Research

Compared with transistors based on inorganic semiconductors, organic transistors can be fabricated at much lower temperatures of about 100 degrees Celsius. This makes it possible to manufacture electronic systems on a variety of unconventional substrates, such as plastics, paper and textiles. As this type of electronic systems is of interest for mobile applications, it is critical that the transistors and circuits can be operated at very low supply voltages. We have therefore developed an ultra-thin gate dielectric that reduces the required supply voltage to 0.7 Volt.

Higgs spectroscopy of superconductors in nonequilibrium

2018 Schwarz, Lukas; Fauseweh, Benedikt; Manske, Dirk

Chemistry Material Sciences Quantum Physics Solid State Research

In superconductors, a collective excitation of Cooper pairs exists which is known as the Higgs mode. If the system is excited out of equilibrium, Higgs oscillations can arise. From these, properties of the superconducting energy gap can be deduced. In conventional superconductors the system oscillates with a frequency corresponding to two times the energy gap. In the case of unconventional superconductors multiple Higgs modes can arise. As a consequence, Higgs oscillations can serve as a spectroscopic method to retrieve information about the symmetry of the energy gap.

Quantum chemical approaches to electronic structure theory for materials

2017 Grüneis, Andreas; Alavi, Ali

Chemistry Material Sciences Solid State Research

Quantum chemical approaches to the description of the electronic structure of real materials can be used to predict even strong electronic correlation effects with high accuracy. However, the scaling of the computational complexity to calculate and store the true many-electron wave function often makes these methods intractable. In this review we report on recent progress to reduce the computational complexity of wave function based methods for the study of molecules and solids.

Ultrafast Lithium between two graphene layers

2017 Kühne, Matthias; Paolucci, Federico; Popovic, Jelena; Maier, Joachim; Smet, Jurgen H.

Chemistry Material Sciences Solid State Research

In analogy to lithium-ion technology, bilayer graphene is employed as an electrode in an electrochemical cell for the first time. An innovative cell design allows for the application of electronic transport methods known from the field of nanostructures and low-dimensional systems. This unusual combination offers unprecedented direct access to the motion of lithium-ions that may be reversibly inserted in between the two carbon sheets of bilayer graphene. An ionic mobility much higher than in bulk graphite can thus be revealed.

The exotic faces of entangled electrons in solids

2016 Takagi, Hidenori

Chemistry Material Sciences Solid State Research

In transition metal compounds, electrons are strongly entangled (correlated) by Coulomb interaction and forms a rich variety of solid, liquid and gas phases. We are aiming to explore exotic electronic phases formed by spin, charge and orbital degrees of freedom of entangled electrons. In this review, we report that by incorporating relativistic spin-orbit coupling, entanglement of spin and motion of electrons, in complex iridium oxides, even richer phases of correlated electrons emerge including spin orbital electron solid (Mott insulator), Dirac electron gas and Quantum spin liquid.
