Fig. 10.1 a Wannier excitonic nature of doping. A hole loosely bound around the negatively
ionized acceptor ion (Fe 2 Cl 6
− ) in the rubrene single crystal showed 24% doping efficiency. Band
conduction promotes the carrier generation by doping. b Combination of two types of organic
crystals exhibiting hole and electron band conduction. Exciton automatically dissociates into free
electron and hole at room temperature. c Single organic crystal with bipolar band-conductive nature.
Exciton automatically dissociates into free electron and hole in the single organic crystals at room
temperature. a Reproduced with permission from M. Hiramoto et al., Adv. Mater Copyright 2018
