Abstract

We report scanning Kelvin probe microscopy (SKPM) of electrically biased difluoro bis(triethylsilylethynyl) anthradithiophene (diF-TESADT) organic thin film transistors. SKPM reveals the relationship between the diF-TESADT film structure and device performance. In these devices charge transport is limited by the structure and interaction of the diF-TESADT grains within the active portion of the device rather than by the electrical contacts between the organic semiconductor and the source and drain electrodes.
