Mid-Term Report Summary - LAYERENG-HYBMAT (Molecular-Layer-Engineered Inorganic-Organic Hybrid Materials)

Layer-engineered inorganic-organic hybrid materials have the capacity– once carefully designed and fabricated – to exhibit tailored combinations of properties traditionally seen for inorganics or organics separately. An elegant, yet industrially feasible way to realize this is to combine the state-of-the-art gas-phase thin-film deposition technique of inorganics, i.e. ALD (Atomic Layer Deposition), with the emerging MLD (Molecular Layer Deposition) technique for organics. The combined ALD/MLD technique enables the atomic/molecular layer-by-layer fabrication of inorganic-organic hybrid thin films through sequential self-limiting gas-surface reactions with high precision for the film thickness and composition. In the LAYERENG-HYBMAT project we have widened the horizons of the ALD/MLD technique and developed novel processes for tens of different inorganic and organic components; the resultant fundamentally new types of layer-engineered hybrid thin-film materials possess a property palette not accessable with conventional materials. In particular, we have fabricated oxide-organic thin-film superlattices in which the periodically introduced single/thin organic layers between oxide layers are shown to hinder phonon transport and enhance the thermoelectric properties of the films. Other examples of the exciting application areas foreseen for the ALD/MLD hybrid thin films include the flexible and transparent Li-ion microbattery materials and flexible thin films of metal organic framework (MOF) materials for e.g. gas sensing and storage and catalysis.
