Chemical Mechanisms for Injection of Positive Carriers into Single Crystals

Abstract

NUMEROUS oxidants, the standard potentials of which are high enough to oxidize anthracene, form hole injecting contacts with it1,2. Carrier injection occurs by a wholly electrochemical process, the transfer of an electron from solid to dissolved oxidant. Anthracene oxidizes in homogeneous solution at 1.09 V with respect to a saturated calomel electrode (SCE)3.
