Welcome

The Helmholtz Research Programme STN (Science and Technology of Nanosystems) takes on the challenge of controlling and shaping materials from the atomic and molecular up to the macroscopic scale to explore their entire potential of novel functionalities.

STN is dedicated towards research and development of

Our activities span the entire range from fundamental science to high performance technologies and integrated systems. We closely cooperate with the Karlsruhe Nano Micro Facility (KNMF) as a large-scale user facility for multimaterial nano and micro technologies.

Gips-Schüle Research Award for Ultracompact Photodetector

November 29, 2017

Researchers of Karlsruhe Institute of Technology (KIT) demonstrated a novel plasmonic photodetector that is a hundred times smaller and much quicker than conventional detectors. For this, scientists Sascha Mühlbrandt, Christian Koos, and Manfred Kohl of KIT were granted this year’s Gips-Schüle Research Award in the amount of EUR 50,000 by the Gips-Schüle Foundation. Large numbers of these small components can be integrated on large-area silicon wafers, together with other optical and electronic components. In this way, capacity of future communication systems can be increased considerably.

Research into Terahertz Signals and Friction-optimized Metals

November 28, 2017

At Karlsruhe Institute of Technology (KIT), Professor Christian Koos combines photonic and electronic methods to generate terahertz signals and to make them usable for data transmission and measurements. Dr. Christian Greiner studies the behavior of metals in friction contacts in order to reduce friction and wear and, thus, decrease the consumption of energy and raw materials. The European Research Council (ERC) has now decided to award Consolidator Grants to both scientists. In the next five years, their projects will be funded with about EUR 2 million each.

Science: Metamaterial with a Twist

November 24, 2017

Using 3D printers for the microrange, researchers of KIT have succeeded in creating a metamaterial from cubic building blocks that responds to compression forces by a rotation. Usually, this can only be achieved by transmission using a crankshaft, for instance. The sophisticated design of bars and ring structures and the underlying mathematics are now presented in the latest issue of Science.

Quantum Computing with Molecules for a Quicker Search of Unsorted Databases

November 13, 2017

Scrapbooks or social networks are collections of mostly unsorted data. The search for single elements in very large data volumes, i.e. for the needle in the data haystack, is extremely complex for classical computers. Scientists of Karlsruhe Institute of Technology (KIT) have now quantum mechanically implemented and successfully executed Glover’s algorithm, a process for the quick finding of a search element in unsorted databases. Their results are reported in the Physical Review Letters. DOI: 10.1103/PhysRevLett.119.187702

Ceria Nanoparticles: It Is the Surface that Matters

October 30, 2017

Exhaust gas cleaning of passenger cars, power generation from sunlight, or water splitting: In the future, these and other applications may profit from new findings relating to ceria. At Karlsruhe Institute of Technology (KIT), scientists have studied ceria nanoparticles with the help of probe molecules and a complex ultrahigh vacuum-infrared measurement system and obtained partly surprising new insights into their surface structure and chemical activity. Work is reported in three articles published in the journal Angewandte Chemie (applied chemistry).

3D Microprinting: Security for Products, Passports, and Money

October 25, 2017

Security features are to protect bank notes, documents, and branded products against counterfeiting. Losses caused by product forgery and counterfeiting may be enormous. According to the German Engineering Association, the damage caused in 2016 in its branch alone amounted to EUR 7.3 billion. In the Advanced Materials Technologies journal, researchers of Karlsruhe Institute of Technology (KIT) and the ZEISS company now propose to use printed 3D microstructures instead of 2D structures, such as holograms, to improve counterfeit protection.

Butterfly Wing Inspires Photovoltaics: Light Absorption Can Be Enhanced by Up to 200 Percent

October 19, 2017

Sunlight reflected by solar cells is lost as unused energy. The wings of the butterfly Pachliopta aristolochiae are drilled by nanostructures (nanoholes) that help absorbing light over a wide spectrum far better than smooth surfaces. Researchers of Karlsruhe Institute of Technology (KIT) have now succeeded in transferring these nanostructures to solar cells and, thus, enhancing their light absorption rate by up to 200 percent. The scientists report their results in the journal Science Advances. DOI: 10.1126/sciadv.1700232.
