Interface formation
Interface formation between small organic ring molecules and III-V (001) surfaces
The bonding mechanism and bonding sites of organic molecules on semiconductor surfaces are influenced by intra-molecular properties as well as atomic configuration of the surfaces. In order to find and analyse the driving forces behind the interface formation we use a multi-method concept including optical probes, standard surface analytics and numerical analysis in cooperation with the group of W.G. Schmidt (University Paderborn). On this purpose the influence of different substrates and adsorbates onto the interface formation is investigated. Small organic ring molecules with different functional groups and 3d-structure are deposited onto III-V semiconductor surfaces which differ in their respective dimer configuration.
