One attribute that influences the optoelectronic property of these organic semiconductors is their "exciton binding energy," which is the energy needed to divide an exciton into its negative and ...

The energy needed to generate the free-charge carriers is referred to as exciton-binding energy. The lower the exciton-binding energy, the easier it is to generate free-charge carriers ...

Exciton binding energy is of the order of 10 meV and exciton lifetime is about 1 μs at low temperatures with zero applied voltage. The lifetime can be controlled by the applied voltage over ...

Quantum confinement enhances the binding energy of excitons, which are electron-hole pairs formed upon light absorption. The increased exciton binding energy results in stronger light-matter ...
