Anotace:

Organic molecules classified as high-performance pigments receive increased interest not only because of their color properties but rather as a powerful, highly tunable, cheap and environment-friendly material for organic electronics [1]. At the opposite end of electronic industry dominates silicon, the basic material in inorganic semiconductor technologies. As interfaces become crucial with ongoing miniaturization, Si surfaces are subjected to wide-spread research. Specifically, Si surfaces functionalized by metal atomic layers exhibit exotic electronic states, such as anomalous spin splitting [2], 2D superconductivity [3] or 2D topological states [4].

The focus of this PHD thesis is to study at atomic level interaction of the molecules from high-performance pigments family on metal-functionalized Si surfaces. The aim is to tune the surface exotic properties by the molecular superstructures. As the main tool, scanning tunneling microscopy (STM) will be used, allowing to probe both molecular and electronic structure of spontaneously grown assemblies. The study will be in collaboration with chemists engineering and synthesizing novel organic samples and with theoreticians providing ab-initio calculations of relation between atomic and electronic structure.

The thesis will contribute to future utilization of hybrid organic-inorganic systems in nano-electronic devices.

The applicant will be motivated to spend 6+months abroad with one of our collaborators.
