The pre-patterning of a surface to obtain locally arranged nanostructures is usually done by complex patterning techniques like electron beam lithography, focused ion beam etching or ion implantation. These direct surface patterning techniques can cause crystal damage and defects degrading the quality and performance of the nanostructured elements. Other disadvantages are that these techniques only have short-range impact and are incompatible with batch processing.<br> A method for fabricating layer assemblies with locally arranged nano-structures. A buried, selectively modified underlying layer is used to control the growth of nanostructures on the surface by controlling the laterally inhomogeneous strain distribution. This is done using standard lithography, etching and oxidation techniques. <br> <br> <strong>Benefits</strong><br>

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
