A new measuring method helps understand the physics of high-temperature superconductivity
From sustainable energy to quantum computers: high-temperature superconductors have the potential to revolutionize today’s technologies. Despite intensive research, however, we still lack the necessary basic understanding to develop these complex materials for widespread application. "Higgs ...
Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater for the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor materials. They are not only supposed to cover a broad range of wavelengths ...
Research team presents novel transmitter for terahertz waves
Terahertz waves are becoming ever more important in science and technology. They enable us to unravel the properties of future materials, test the quality of automotive paint and screen envelopes. But generating these waves is still a challenge. A team at Helmholtz-Zentrum Dresden-Rossendorf ...
New encapsulation technique protects electronic properties of sensitive materials
Tomorrow’s electronics are getting ever smaller. Researchers are thus searching for tiny components that function reliably in increasingly narrow configurations. Promising elements include the chemical compounds indium selenide (InSe) and gallium selenide (GaSe). In the form of ultra-thin layers, ...
Experiment comes up with important steps towards optimizing water electrolysis
Laboratory experiments and a parabolic flight campaign have enabled an international team of researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) to gain new insights into water electrolysis, in which hydrogen is obtained from water by applying electric energy. Water electrolysis ...
Scientists assess the potential of magnetic-cooling materials
Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into our daily lives causes a rapidly growing ecological footprint. New ...
Research team develops a new principle to generate terahertz radiation
The "Landau-level laser" is an exciting concept for an unusual radiation source. It has the potential to efficiently generate so-called terahertz waves, which can be used to penetrate materials as well as for future data transmission. So far, however, nearly all attempts to make such a laser ...
Laboratory experiments show that semiconductor nanowires can be tuned over wide energy ranges
Nanowires promise to make LEDs more colorful and solar cells more efficient, in addition to speeding up computers. That is, provided that the tiny semiconductors convert electric energy into light, and vice versa, at the right wavelengths. A research team at Helmholtz-Zentrum Dresden-Rossendorf ...
Researchers modify magnetic behavior of exotic materials
People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. They do so whenever their elementary magnets, the magnetic spins, cannot align properly. Cesium copper chloride (Cs2CuCl4) – or CCC for short – is a prime example of frustrated materials. In this ...
A team of researchers generates ultra-short spin waves in an astoundingly simple material
Due to its potential to make computers faster and smartphones more efficient, spintronics is considered a promising concept for the future of electronics. In a collaboration including the Max Planck Institute for Intelligent Systems (MPI-IS) and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a ...
