High‐Performance Organic Single‐Crystal Transistors on Flexible Substrates

Flexible and conformable organic single crystals as thin as 150 nm are used for fabricating mechanically bendable organic single-crystal field-effect transistors on low-cost plastic substrates (see figure and cover). We report effective field-effect mobility as high as 4. 6 cm2 V–1 s–1 for a flexible rubrene single-crystal transistor, on/off ratio of ca. 106, threshold voltage of – 2. 1 V, and a normalized subthreshold swing of 0. 9 V nF decade–1 cm–2.
