ORGANIC SOLID/SOLID WETTING DEPOSITION (OSWD)


We developed and apply a novel technique (OSWD) to generate self-assembled monolayers of organic semiconductors on substrate surfaces. The technique enables to grow monolayers of insoluble organic molecules without the need for vacuum conditions (as in the case of Molecular Beam Epitaxy) or chemical modifications (to achieve solubility).

GRAPHENE DOPING


Graphene is a one-atom thick carbon sheet with exceptional properties. Tuning the electronic structure of Graphene is important for the development of carbon based electronics. We develop graphene doping methods which work fully under ambient conditions.


ORIGIN OF LIFE


Following the bottom-up approach to the study of the origin of life we address the question of which environments are capable to induce self-assembly of probable primordial molecules on mineral surfaces. Our results on insoluble PAH molecules show that a solution is not a general prerequisite for self-assembly under ambient conditions. [more]


BIOORGANIC SEMICONDUCTORS


We grow two-dimensional networks of bio-organic molecules and their coordination complexes with metal atoms via OSWD and investigate their semiconducting properties for applications within the field of NanoBioTechnology. [more]


NANOSCALE GUIDED SELF-ASSEMBLY


With an approach which we term "locally guided growth”, self-assembly and nanomanipulation occur simultaneously. Here, the role of nanomanipulation is just to induce information about the direction of growth of nanostructures, whereas the formation results purely from OSWD self-assembly. [more]


LOCALLY INDUCED CO-ADSOPTIONS


Organic semiconductor monolayers can locally be doped with domains of a chemically different, second compound at predefined sites down to the range of about 30 nm. We achieve this by combining OSWD with a dip-pen like STM approach. [more]


MOLECULAR DATA STORAGE


Information can be stored in OSWD grown monolayers via nanoextraction. The stability of the data arises by the fact that the semiconductors are suspended in a matrix in the form of nanocrystals instead of being dissolved as single molecules. [more]
