Abstract


This study investigates organic semiconductor thin films produced by mist deposition using advanced scanning probe microscopy (SPM) methods. Mist deposition is presented as a cost-effective, scalable alternative to vacuum evaporation for fabricating flexible organic electronics. The technique reliably forms uniform films of n-type semiconductors such as fullerene (C60) and PCBM. SPM techniques—including AFM, KFM, and SCFM—are applied to examine film morphology, surface properties, and nanoscale phase separation. Findings demonstrate that mist deposition, alongside SPM analysis, enables efficient optimization and improved performance in next-generation organic semiconductor devices.
