For a ‚Green‘ Microchip

Sibylle does not own a smartphone. „This is my personal way to limit the information flood“, the 45-year-old scientist says. At the Helmholtz-Zentrum Dresden-Rossendorf, she works on reducing the energy consumption of microchips to make them ecologically more efficient. Within the Silicon Nanowire Path, her research focuses on the properties of electronic elements in the nanometer rage, such as molecules, clusters, wires, tubes, films and complex composites. Her aim is a scale-adapted and multi-scale description of material properties under the influence of external factors and their validation in experiments.

Sibylle’s material analysis results in Rossendorf furnish a base for application-oriented developments such as the NaMLab works on. Here, the team of Path Leader, Thomas Mikolajick, succeeded in constructing the worldwide first universal transistor. His team demonstrated an energy-efficient circuit with one single transistor type instead of the two different types used in conventional electronics. This new technology could change the current major CMOS technology significantly, enabling a single technology with enhanced functionality.

„I appreciate the unique cfaed network of outstanding research institutions“, the material scientist says. Sibylle is also head of a research team in the virtual Helmholtz institute called ‚Memriox‘ which unites scientists of the universities in Dresden, Freiberg, Jena, Chemnitz, the Helmholtz centers in Dresden-Rossendorf and in Jülich as well as the University of California in San Diego, USA and the ETH Zurich in Switzerland. Here, she develops new materials for ion-tailored oxide-based memristive elements.

In January 2013, she was appointed to a professorship of Technische Universität Chemnitz with the focus on nanoscale material characteristics. Furthermore, Sibylle was granted € 1 milion by a program for excellent female scientists of the Helmholtz Association. After a PhD in chemistry at the TU Munich she habilitated in physics at Technische Universität Chemnitz. Her husband, a scientist at the Leibnitz Institue for Solid State and Materials Research Dresden, is also affiliated to cfaed. „Of course, working in the same place is optimal for us as a family“, Sibylle says. Thus, the Bavarian cannot imagine a better research location than ‚Silicon Saxony‘.
