Tilted pulses

Extremely short and specifically-shaped electron pulses for materials studies in the femtosecond and attosecond range


Our world is basically made up of atoms and electrons. They are very small and move around very rapidly in case of processes or reactions. Although seeing atoms is nowadays possible, for example with modern electron microscopes, tracking atomic movements requires ultrashort measurement periods in ...

The limits of friction


Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to set a stationary object in motion, its static friction must be overcome ...

Stable quantum bits


Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland develop a stable quantum gate for two-quantum bit systems made of silicon. The quantum gate is able to perform all necessary basic operations of the ...

A material with promising properties

Successful synthesis of an important ferromagnetic semiconductor


The Collaborative Research Centre CRC 1214 at the University of Konstanz has developed a method for synthesising Europium (II) oxide nanoparticles - a ferromagnetic semiconductor that is relevant for data storage and data transport Ferromagnetic semiconductors have attracted increasing attention ...

Breakthrough with a chain of gold atoms

Breakthrough in understanding heat transport


The precise control of electron transport in microelectronics makes complex logic circuits possible that are in daily use in smartphones and laptops. Heat transport is of similar fundamental importance and its control is for instance necessary to efficiently cool the ever smaller chips. An ...


Single electrons at top speed

Physicists control currents ten thousand times faster than high-speed electronics


At the University of Konstanz, the Chair for Ultrafast Phenomena and Photonics succeeded in controlling the movement of single electrons on attosecond timescales. One attosecond is the billionth part of a billionth second. The electric field of ultrashort light pulses in this process determines ...

Natural mother of pearl structure, synthetic replication


Biomaterials play a crucial role in the development of future high-performance materials. A naturally occurring example of such biomaterial, the mollusk shell, guides chemical replication processes in laboratories. Due to its complex chemical construction, however, these processes are not easy to ...


Advances in Molecular Electronics: Lights On – Molecule On


Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of Konstanz are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported in the ...


Sulphur Atoms in the Metal Centre

A team of researchers has discovered a new binding site for nitrous oxide (N2O)


Nitrous oxide (N2O) harms the earth’s climate in two ways. First, N2O is a colourless and odourless greenhouse gas that is 300 times stronger than carbon dioxide (CO2). Second, under the effect of cosmic radiation, it contributes to the destruction of the ozone layer, like halocarbons, or ...
