ORGANIC SOLID/SOLID WETTING


We developed a novel technique which we call Organic Solid/Solid Wetting Deposition (OSWD). It allows for growing monolayer of insoluble organic semiconductor molecules on substrates without the need for chemical modifications to achieve
solubility or deposition techniques requiring vacuum conditions. [more]


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 based on OSWD which work fully under ambient conditions. [more]


NANOFLUIDICS WITH ORGANIC SOLIDS


Temporal nanoconfinements of water between dispersed organic crystals and a substrate surface enables us to catalise OSWD reactions under ambient conditions for functionalizing surfaces. Applications are within the field of carbon-based electronics. [more]


LOW-DIMENSIONAL CRYSTAL ENGINEERING


We grow one-dimensional nanostructures and two-dimensional supramolecular crystals of organic semiconductors on substrates under ambient conditions directly from three-dimensional organic crystals. The approach is based on OSWD and does not require dissolving, melting or evaporating of the source crystals. [more]


PREBIOTIC CHEMISTRY


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. Our results on insoluble heterocyclic molecules show that a solution is not a general prerequisite for supramolecular self-assembly. [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]



Former Projects:


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]
