Florian Aigner, Vienna University of Technology Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas was created in strontium titanate. In a thin layer just...

Discovery advances novel devices Chinese researchers, reporting in the Journal of Applied Physics, published by the American Institute of Physics, have described a new breakthrough in understanding the way electrons travel around quantum dots. This might lead to promising new fabrication methods of novel quantum devices. Guodong Li and colleagues at the National Center for Nanoscience and Technology in Beijing carried out an experiment using self-assembled quantum dots and a two-dimensional...

With its new molecular beam epitaxy facility, PTB continues to be the only metrology institute to produce primary quantum Hall effect resistance standards For a long time, the electrical units are feeling at home in the quantum world. In the endeavor to trace the entire International System of Units (SI) back to natural constants, they have long been in the lead - because, among other things, the resistance can be realized with the aid of the quantum Hall effect. The Physikalisch-Technische...
