Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

Physicists at JGU discovered: Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and continue to rise. However, if chips, processors and the like are based on electric current, there are limits to miniaturization.

Researchers find new material with significant potential for electronics applications Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team at the Technical University of Munich (TUM) has now discovered a material that makes it possible to create a diode with a simple change in temperature.

International research team led by Göttingen University controls interaction of charge carriers An international research team led by the University of Göttingen has detected novel quantum effects in high-precision studies of natural double-layer graphene and has interpreted them together with the University of Texas at Dallas using their theoretical work.

A low-cost and easy-to-manufacture lighting technology can be made with light-emitting electrochemical cells. Such cells are thin-film electronic and ionic devices that generate light after a low voltage is applied. Researchers at the Technical University of Munich (TUM) and the University of Turin have now used extensive data analysis to create first-class electrochemical cells from copper complexes that emit blue and white light.

Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.

Toward a new kind of superconductivity: An international team of physicists finds joint appearance of intricate quantum phenomena. Toward a new kind of superconductivity: In the past four years scientists have discovered metals whose crystal structure mimics that of a traditional Japanese woven bamboo pattern: kagome metals.

In the spirit of the energy transition, TU Ilmenau is developing a resource-efficient power distribution grid for Germany. Such a power grid, based on direct current technology, will be specifically tailored to the increasing use of renewable energy generated in a large number of decentralized plants and will offer significantly higher operational reliability than the current grid.
