9. Some highly purified crystalline organic materials such as anthracene transport both carrier types, however, they are not typically employed as transistor active in layers. See, for example, N. Karl, Mol. Cryst. Liq. Cryst. 171, 157 (1989).

11. Positive carriers are hereafter referred to as holes and negative carriers as electrons, although it is recognized that in such materials it is likely that the conducting species are polarons.

14. This happens as a result of effective trapping of the other carrier. We note that it may be possible in the future to synthesize ultrapure organic materials which transport both carrier types.
