Abstract:

Photogeneration of free carriers in anthracene single crystals with strongly absorbed light has been studied under ultra-high vacuum UHV conditions. Single crystals of zone-refined synthetic anthracene were mounted in a modified sandwich cell set-up 2 in the UHV system. The generation mechanisms for both electrons and holes were found to depend markedly on the extent of evaporation of the crystal. This removal of the surface layers reduced the amount of singlet exciton dissociation at the surface, allowing the exciton-exciton collision generation mechanism to predominate. Author
