Abstract

Transport and optical properties of organic molecular crystals depend on the presence and distribution of crystallographic defects. In this paper we overview the impact of defects on properties of single crystal rubrene, an organic material with the highest to date hole mobility. We show that the defects strongly affect the mobility and carrier concentration in rubrene.
