Research Abstract

we have successfully designed and fabricated a large area dewetting apparatus. We could show that it is possible to coat a large area substrate (30x40cm) homogeneously with polymer or low molar mass compounds, forming micronsize droplet or fiber arrays. Possible applications are microlens arrays or organic field effect transistor arrays.
