DFG Project within RTG 2767
In situ and in operando characterization of functional self-assembled nanostructures
Funding Period: 2022-2026
The main goal of the project is to gain a better understanding and control of the self-assembly processes employed for both the growth and assembly of nanoscopic functional elements throughout the Research Training Group RTG 2767.
To this end, liquid phase electron microscopy (LPEM) will be used to directly observe the assembly of functional hybrid nanostructures. The work will first focus on the DNA-mediated assembly of nanomaterials and novel nanoactuators based on Au nanorods attached to DNA origamis. These investigations will allow the identification and optimization of kinetic parameters, such as the mobility and aggregation of specific ingredient, that limit the assembly processes. The results of the self-assembly will be characterized with analytical high-resolution (scanning) transmission electron microscopy (HR-(S)TEM). The electrically biased switching of nanoactuators is planned to be monitored in real time.Electrical properties of functional elements are essential for their use in electronic devices. In the long run, LPEM will be used in combination with in situ electrical measurements to characterize the quality and kinetics of the metallization of these elements. We will implement and develop low dose strategies (compressive sensing; inpainting) and conduct ex-situ control experiments to quantify and minimize artefacts.
