Cover Picture: High-Performance Organic Single-Crystal Transistors on Flexible Substrates (Adv. Mater. 17/2006)



The cover shows a comparison of thin and thick rubrene single crystals where the flexibility of the thin rubrene crystals is clearly illustrated. On p. 2320, Yang, Bao, and co-workers report that high performance flexible transistors on plastic substrates fabricated by using these rubrene “thin-film” single-crystals demonstrate mobility as high as 4.6 cm2 Vs–1 and ON/OFF ratios of approximately 106.
