24_41/2012Organic Field-Effect Transistors: Direct Structural Mapping of Organic Field-Effect Transistors Reveals Bottlenecks to Carrier Transport (Adv. Mater. 41/2012)

Organic thin film transistors are commonly solution-processed on pre-patterned substrates which can strongly and negatively influence the solidification and crystallization behaviors of the semiconductor causing a reduction in carrier mobility. On page 5553, Aram Amassian and co-workers demonstrate an X-ray microbeam technique capable of mapping the microstructural variations of the organic semiconductor within the channel of real devices; the insight is used to reduce bottlenecks to charge transport.
