    • 4PENT has four methyl groups and due to the difference in molecular occupation of the unit cell (4 vs. 2) we believe comparison of unit cell volumes may not be very meaningful.

    • It is somewhat unusual for bottom-contact devices to have larger mobilities than top-contact devices usually because organic semiconductors tend to form small grains on Au electrodes, resulting in high contact resistance. On the other hand, deposition of metal on organic semiconductors in the top-contact mode may cause damage to the semiconductor and also result in increased contact resistance. In this case, perhaps the grain structure between gold and the organic afforded better contact for bottom-contact devices.

    • The reorganization energy (A) for self-exchange corresponds to the sum of the geometry relaxation energies upon going from the neutral-state geometry to the charged-state geometry and vice versa. These two portions of λ are typically nearly identical, see: M. Malagoli, J. L. Brédas, Chem. Phys. Lett. 2000, 327, 13.
