Charge injection phenomena at the contact interface between (5,10,15,20-tetramethylporphyrinato)cobalt(ii) and 2,5-difluoro-7,7,8,8-tetracyanoquinodimethane single crystals

Abstract

Charge transfer phenomena occurring at the contact interface of heterogeneous organic crystals are investigated. About 10% more charge was injected into the crystal interface by the contact, which largely increased the surface conductivity.
