AB - Over the past three decades, significant research efforts have focused on improving the charge carrier mobility of organic thinfilm transistors (OTFTs). In recent years, a commonly observed nonlinearity in OTFT current–voltage characteristics, known as the “kink” or “double slope,” has led to widespread mobility overestimations, contaminating the relevant literature. Here, published data from the past 30 years is reviewed to uncover the extent of the fieldeffect mobility hype and identify the progress that has actually been achieved in the field of OTFTs. Present carriermobilityrelated challenges are identified, finding that reliable hole and electron mobility values of 20 and 10 cm2 V−1 s−1, respectively, have yet to be achieved. Based on the analysis, the literature is then reviewed to summarize the concepts behind the success of highperformance ptype polymers, along with the latest understanding of the design criteria that will enable further mobility enhancement in ntype polymers and small molecules, and the reasons why high carrier mobility values have been consistently produced from small molecule/polymer blend semiconductors. Overall, this review brings together important information that aids reliable OTFT data analysis, while providing guidelines for the development of nextgeneration organic semiconductors.
