Winzige Nanostrukturen erlauben ausgezeichnete Kontrolle über einzelne Elektronen.
Combining two ultra-thin material layers yields new possibilities for quantum electronics. A research team with members from TU Wien presents strongly tunable quantum systems. Two novel materials, each composed of a single atomic layer and the tip of a scanning tunneling microscope - these are the ingredients to create a novel kind of a so-called "quantum dot". These extremely small nanostructures allow delicate control of individual electrons by fine-tuning their energy levels directly. Such devices are key for modern quantum technologies. The theoretical simulations for the new technology were performed in the team of Prof. Florian Libisch and Prof. Joachim Burgdörfer at TU Wien. The experiment involved the group of Prof. Markus Morgenstern at RWTH Aachen and the team around Nobel-prize laureates Andre Geim and Kostya Novoselov from Manchester who prepared the samples.
