Highly Charged Ions Melt Nano Gold Nuggets
Tiny structures made of gold can be specifically manipulated by ion bombardment at TU Wien (Vienna) - surprisingly, the decisive factor is not the force of the impact. Normally, we have to make a choice in physics: Either we deal with big things - such as a metal plate and its material properties, or with tiny things - such as individual atoms.

Increasing the storage time of quantum information in semiconductor nanostructures.
Countries and corporations around the world are researching a completely new type of computer - quantum computers. But the road to usability is arduous. Researchers at Johannes Kepler University Linz have succeeded in making progress in the storage of quantum information as part of an international collaboration.

Speed Limit of Computers detected
By Christoph Pelzl One million gigahertz: This is the physical limit of the signal speed in transistors, as a German-Austrian physics team has now discovered. The maximum speed of signal transmission in microchips is about one petahertz (one million gigahertz), which is about 100,000 times faster than current transistors.

Computer designs magnonic devices
Magnonic devices have the potential to revolutionize the electronics industry. Qi Wang, Andrii Chumak from University of Vienna and Philipp Pirro from TU Kaiserslautern have largely accelerated the design of more versatile magnonic devices via a feedback-based computational algorithm. Their "inverse-design" of magnonic devices has now been published.

New measurements call spin liquids into question
Is it possible to transmit information through a material in the form of electron spins? New measurements show: not in the way that scientists had been working on for decades. It is an old dream of solid-state physics: "spin liquids" are a hypothetical state of matter with exotic magnetic properties.

Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.

TU Graz starts CD laboratory for multifunctional and highly integrated electronic components
By Susanne Eigner The Christian Doppler Laboratory for Technology-Guided Electronic Component Design and Characterization investigates ways to better control electromagnetic interactions in smart networked devices, especially in the 5G frequency range. In smartphones and many other complex, wirelessly networked devices, sophisticated technologies are used to integrate the individual electronic components into the housing.

Physicists Discover New Magnetoelectric Effect
In a very unusual way, the electrical and magnetic properties of a particular crystal are linked together - the phenomenon was discovered and explained at TU Wien (Vienna). Electricity and magnetism are closely related: Power lines generate a magnetic field, rotating magnets in a generator produce electricity.

New Materials for Extra Thin Computer Chips
For a long time, something important has been neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials. Ever smaller and ever more compact - this is the direction in which computer chips are developing, driven by industry. This is why so-called 2D materials are considered to be the great hope: they are as thin as a material can possibly be, in extreme cases they consist of only one single layer of atoms.

Novel Electric Impulses Relieve the Pain
Stimulating the vagus nerve in the ear can help relieving chronic pain. TU Wien and MedUni Vienna have developed novel, sophisticated methods for electric stimulation of the vagus nerve. The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear.

Researchers observe shortest magnetic event
By Christoph Pelzl For the first time ever, physicists have been able to change the magnetic moment of a material using a light wave within one femtosecond - the fastest magnetic event ever observed. Additional at the end of the text Electronic properties of materials can be directly influenced via light absorption in under a femtosecond (10 -15 seconds), which is regarded as the limit of the maximum achievable speed of electronic circuits.

How to Freeze Heat Conduction
Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy. Every day we lose valuable energy in the form of waste heat - in technical devices at home, but also in large energy systems.

First diode for magnetic fields
Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications. Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one.

Using electricity to switch magnetism
At TU Wien, a major step has been taken towards linking electrical and magnetic material properties, which is crucial for possible applications in electronics. It's not exactly a new revelation that electricity and magnetism are closely linked. And yet, magnetic and electrical effects have been studied separately for some time now within the field of materials science.

A particle like slow light
A remarkable discovery was made at TU Wien recently, when particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly. There was great excitement back in 2015, when it was first possible to measure these 'Weyl fermions' - outlandish, massless particles that had been predicted almost 90 years earlier by German mathematician, physician and philosopher, Hermann Weyl.

Magnetic Quantum Objects in a "Nano Egg-Box"
Magnetic quantum objects in superconductors, so-called "fluxons", are particularly suitable for the storage and processing of data bits. Computer circuits based on fluxons could be operated with significantly higher speed and, at the same time, produce much less heat dissipation. Physicists around Wolfgang Lang at the University of Vienna and their colleagues at the Johannes-Kepler-University Linz have now succeeded in producing a "quantum egg-box" with a novel and simple method.

Measured for the first time: direction of light waves changed by quantum effect
The 'quantized magneto-electric effect' has been demonstrated for the first time in topological insulators at TU Wien, which is set to open up new and highly accurate methods of measurement. A light wave sent through empty space always oscillates in the same direction. However, certain materials can be used to rotate the direction in which the light is oscillating when placed in a magnetic field.

Quantum Communication: How to Outwit Noise
Nowadays we communicate via radio signals and send electrical pulses through long cables. This could change soon, however: Scientists have been working intensely on developing methods for quantum information transfer. This would enable tap-proof data transfer or, one day, even the linking of quantum computers.

New Invention for more Efficient Atomic Force Microscopes
Tiny tips on cantilevers are used to scan a surface in an atomic force microscope. A new invention from TU Wien now provides a simpler way to measure the result. The basic principle of the atomic force microscope is very simple: an extremely thin, movable tip on a cantilever is moved over a surface that is being examined.
