Charge-Transfer Exciton State and Energy Levels in Tetracene Crystal

An experimental study of the double-quantum external photoelectric effect in tetracene reveals evidence of an exciton state of energy 2.9 eV different from the normal exciton. This mobile, bulk-generated state is considered to be a charge-transfer (CT) exciton and is most efficiently produced at an...

Description
Summary:An experimental study of the double-quantum external photoelectric effect in tetracene reveals evidence of an exciton state of energy 2.9 eV different from the normal exciton. This mobile, bulk-generated state is considered to be a charge-transfer (CT) exciton and is most efficiently produced at an energy ≥Ec=3.7 eV. We associate Ec with the lower edge of a relatively broad upper conductivity band. Presumably, there are other conducting states Ec′ such that ECT
