Molecules as gears and switches

How to build devices on molecular or atomic scale? A team around Francesca Moresco from the Institute of Materials Science of TU Dresden explains how a molecular assembly can be used as a gear, and how a molecule is used as a switch.

Building atomic wires

Scientists of the Institute of Materials Science of TU Dresden explain how to build atomic wires on a hydrogenated silicon surface. They cover a silicon surface with atomic hydrogen and build atomic wires by removing hydrogen with the tip of the STM.

 The Nanocar of the TU Dresden: The Windmill:

A team of the Chair of Materials Science and Nanotechnology from the TU Dresden participate at the Nanocar Race. Our research focuses on the investigation and manipulation of molecular structures on different surfaces. The nanocar of the TU Dresden consists of four single molecules held together by hydrogen bonding. What are possible advantages of our windmill for the Nanocar Race?

Acenes – On-surface generation of molecular wires

Acenes are known to have excellent electronic properties, but a poor kinetic stability. Therefore, acenes with more than 5 benzene rings are rarely observed. In collaboration with chemists around Diego Peña from the university of Santiago de Compostela, scientists of the Institute of Materials Science of TU Dresden developed a new method to build long acenes under the STM-tip.
