Quality of Anthracene Single Crystals Obtained by Physical Vapor Growth

Quality of anthracene single crystals obtained by the physical vapor growth with the horizontal arranged apparatus was examined by Laue method and atomic force microscopy (AFM). 10 mm size single crystals with minute strains could be obtained with 60 min growth time, and with 10–30 mg source material. Even in case of the occurrence of plane slips, the molecular arrangement can still keep energetically stable by the formation of quarter-monolayer (ML) steps.
