Physics of Surfaces and Interfaces

Prof. Johannes Barth

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.

Assembling dye molecules on surfaces to tune their optical properties

In this project you will use scanning tunnelling microscopy under ultra-high vacuum conditions to provide a single molecule characterisation on how small dye molecules arrange and polymerise on surfaces. Such arrangements are expected to be able to tune the colour of the resulting structure.

Indigo is a natural dye of the namesake colour. Changing the chemical structure of its periphery changes its colour, giving rise to the class of indigoide molecules. Here we will use such a naturally occurring indigoide molecule, specifically chosen for its potential to be further functionalised on a planar metal surface. The aim is to use the insight provided from advanced microscopy characterisation, in order to provide a methodology for nanostructures with tuneable optical properties.

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.
