Abstract
Unique exciton states are being explored for use in quantum information systems. Excitons formed in organic semiconductors are long lived at room temperature owing to their high binding energies, and they can form quantum relevant multiexciton states like the spin-entangled triplet pair which is an intermediate during singlet fission. Electrical measurements of excitons provide complementary measurement to common optical based techniques by probing low density exciton dynamics and dark states. Here we tune singlet fission rates by using varied molecular packing to relate optical and device measurements to aid development of transistor-based exciton measurements.
