Organic Electronics: Spatial Mapping of Morphology and Electronic Properties of Air-Printed Pentacene Thin Films (Adv. Funct. Mater. 25/2014)




M. Shtein and co-workers use guard flow-enhanced organic vapor jet printing for the additive patterning of pentacene thin fifilms in air, and perform in situ X-ray diffraction to relate process variables, oxidation, structural defects, and electronic properties in thin-film transistor applications. The process structureproperty relationship is quantifified, and the field-effect mobility is extrapolated based on the processing conditions. The schematic shown represents the GF-OVJP process with in situ diffraction and contacts for TFT measurements.
