Dr. Ruipeng Li's OFET paper featured on the front cover of Advanced Functional Materials

In printed electronics, the drying semiconductor solution undergoes a solution-to-solid phase transformation that must yield optimal microstructure and performance. In small-molecule organic field effect transistors (OFETs), it is crucial to yield films with large area lamellar coverage with excellent inplane p-stacking.  Aram Amassian and co-workers present new methodology and insight, which help to ensure that the drying solution crystallizes in optimal ways to promote carrier transport in OFETs. 

The paper is titled "Heterogeneous Nucleation Promotes Carrier Transport in Solution-Processed Organic Field-Effect Transistors" and discusses a new way to investigate and control the growth of solution-cast thin films, by combining in-situ quartz crystal microbalance measurements with dissipation capabilities (QCM-D) and in-situ grazing-incidence wide-angle X-ray scattering (GIWAXS) in an environmental chamber.​
