Research Field

Research at E20 aims at the fundamental understanding of interface phenomena and their control for the design of functional nanoarchitectures in reduced dimensions. We investigate and manipulate individual nano-objects and highly organized supramolecular systems.

Utilizing scanning probe microscopy tools we examine the interior of complex molecules and develop self-assembly protocols for nanotextured surfaces. With advanced spectroscopy techniques we study charge transfer and electronic reconfiguration processes at ultimate temporal resolution. These activities promote the development of novel bottom-up fabrication methodologies and the molecular-level engineering of materials with tailored properties.

Foldamers on solid surfaces: tethering, folding and assembly

Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. For practical applications, it is desirable to support such self-assembled structures on surfaces. With this project we wish to expand the capabilities of self-assembled molecular layers by mimicking the ability of biomolecules, such as proteins, to fold into well-defined conformations.

Therefore, we will investigate the on-surface self-assembly of a series of foldamers: synthetic molecular strands that fold into helices. For controlling the surface deposition in the solid/vacuum interface, we will employ a home-developed electrospray controlled ion beam deposition (ES-CIBD). Scanning tunnelling microscopy (STM) under ultra-high vacuum conditions will be used as a convenient tool to provide real-space information about the molecular adsorption, conformation and self-assembly. The conformation and assembly will be controlled by thermal processing and choice of solid support.

Tethering of molecular sensitizers on solar cell surfaces

Titanium dioxide is a semiconductor widely used in solar cells. To harness the energy of the solar spectrum, it is sensitised with dyes which are bound by single or dual tethers. Most commonly these anchors are carboxylate groups, however catecholates and hydroxamates are also reported as convenient and robust alternatives.

With this project we aim to provide a comparative study on the microscopic events that lead the different tethers to guide the adsorption of molecular dyes on model titania surfaces. Scanning tunnelling microscopy under ultra-high vacuum conditions and at a temperature range of 250 to 350 K will be used as a convenient tool to provide real-space information about the adsorption and diffusion of single and dual anchors on single crystal surfaces of titanium dioxide.
