High-Mobility Thin-Film Transistors

High-Mobility Thin-Film Transistors

In recent years, semiconducting polymers have been widely studied for their potential applications in low-cost, printed, and flexible electronic devices. Charge transport in semicrystalline polymers is controlled by several influences from crystalline and disordered regions in the material. Salleo et al. report on the structural and morphological characterization of a family of high-mobility thin-film transistors. The authors attribute the improved performance to high mobility in the crystallites rather than trap density. The identification of such relationships between the morphology of the film, its microstructure, and its electronic properties, in turn, leads to a better understanding of transport mechanisms that are of particular relevance towards the design of materials with improved performance. /ab
