Controlling the nanoscale structural and electronic properties of surfaces yields promise for the development of functional nano-patterned solid interfaces. In particular, low-dimensional supramolecular nanoarchitectures with well-defined morphology and electronic structure can exhibit optoelectronic responses which can be exploited in light-harvesting and photocatalytic applications. In order to ensure a hierarchical transfer of function from the nano- to the macro-scale, electronic characterization at the single molecule level is essential.
In the first part of my talk, I will show how protocols of supramolecular chemistry on a surface can be applied to tailor the structural and electronic properties of a solid interface. I will focus on self-assembled biomolecular and metal-organic nano-assemblies on noble metal surfaces. These systems are characterized at the atomic scale by means of low-temperature scanning tunneling microscopy and spectroscopy, and complementary photoelectron spectroscopy.
Optoelectronic functionality of a surface is given by its out-of-equilibrium electron dynamics resulting from an external optical excitation. In a second part of my talk, I will demonstrate the sub-femtosecond generation and control of electronic signals at a solid interface with the electric field of light.
I will finally address my current and future research perspectives, which deal with the bottomup design of photoactive supramolecular nanostructures on a surface, as well as with the realtime characterization of ultrafast photo-induced electron dynamics in such nanosystems.
