Low-Temperature Scanning Probe Microscopy / On-Surface Synthesis
Via low-temperature atomic force microscopy we investigate reaction and self-assembly processes of organic molecules on surfaces. By using a CO-functionalized tip, the so-called “bond imaging technique,” we can visualize the chemical structure of individual molecules and map both inter- and intramolecular bonds. Our main research focus lies on understanding the reactions mechanisms behind on-surface synthesis. On surfaces new functional organic nanomaterials can be produced from molecular building blocks that were not accessible with conventional solution-based synthetic strategies. What is particularly fascinating about such organic nanomaterials is that their (opto-)electronic properties can be tailored solely by their structure, making them a sustainable alternative for applications in photovoltaics, organic electronics, spin-based electronics (spintronics), quantum computers, or topological insulators. Our goal is to decipher the reaction mechanisms of organic molecules on surfaces to be able to produce such quantum materials in a more targeted manner in the future. In addition, we are developing new experimental techniques, such as multi-frequency operation modes for atomic force microscopy, which can be used to improve the imaging properties of the method.
