High Electron Mobility in Air for N,N′‐1H,1H‐Perfluorobutyldicyanoperylene Carboxydi‐imide Solution‐Crystallized Thin‐Film Transistors on Hydrophobic Surfaces

Crossover from band-like to thermally activated charge transport in organic transistors due to strain-induced traps

“…Nanoscale confinement effects during solution processing have also been shown to tune the polymorphism by altering the lattice constants of 6,13-b(triisopropylsilylethynyl)pentacene (TIPS) pentacene films (31). In other studies, the crystals in contact with different surfaces were reported to crack upon cooling, due to strain formation, an effect that was greatly reduced or eliminated with slow cooling (32)(33)(34). In the present work, we focus exclusively on devices for which the cooling/heating is performed sufficiently slowly that no irreversible change (i.e., cracking) is induced.…”

Hybrid organic–inorganic porous semiconductor transducer for multi-parameters sensing

“…PDIF-CN 2 is the material displaying the highest electron mobility (m) in the form of both single crystals [11,12] and thin films [13,14]. In particular, PDIF-CN 2 singlecrystal devices have demonstrated a mobility of about 1-6 cm 2 V 21 s film shows m of about 0.1-0.6 cm 2 V 21 s…”

High-current operation of vertical-type organic transistor with preferentially oriented molecular film

“…The key factor in improving the OTFT performance is to align the crystal axis and π-π stacking direction in the organic film with the carrier transport direction. [5][6][7][8][9][10] Furthermore, the importance of the band conduction has been discussed in recent years. [5][6][7][8][9][10] In conventional planar OTFTs, controlling the grain growth of the polycrystalline film is difficult, which may cause not only a decrease in performance but also a variation in the performance of planar OTFTs.…”

[11][12][13][14] A special fabrication method is necessary to prepare ideal crystalline films, the crystal axis of which is aligned with the channel direction, suitable for planar OTFTs.…”
