説明

<jats:p>Transparent flexible thin-film transistors (tf-TFTs) are an important focus of research since present silicon-based electronics cannot realize such devices. Here, we demonstrate a single-walled carbon nanotube (SWNT) tf-TFTs based on the solution process using transparent electrodes. SWNT tf-TFTs typically exhibit a mobility of 0.5cm2∕Vs and an on/off current ratio of ∼104. More importantly, these transistors are highly flexible and can be bent to a radius of 7.5mm without a significant loss in performance. This study therefore represents a major step towards “SWNT transparent plastic electronics.”</jats:p>
