Abstract

A scanning Kelvin probe microscopy (SKPM) study was conducted for solution-processable organic-thin film transistor (OTFTs) to investigate the role of film microstructure on the performance of device. Thin-film transistors used for the study was made from spun-cast fluorinated 5,11- bis(triethylsilylethynyl) anthradithiophene (diF-TESADT) on pentafluorobenzene thiol (PFBT) functionalized electrodes. It was observed during the study that the mobility of OTFTs strongly depend on the distinct channel length and decreased with an increase in channel length. It was also found that there is a correlation between organic thin-film microstructure and potential drops within the working devices. The study also found that the nature and location of the potential drop change with the device channel length. The study can be used for developing low-cost and solution-processable organic electronic devices.
