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 cm 2 V –1 s –1 for a flexible rubrene single‐crystal transistor, on/off ratio of ca. 10 6 , threshold voltage of – 2.1 V, and a normalized subthreshold swing of 0.9 V nF decade –1 cm –2 .
