Electronic spectrum of the positive polaron and triplet exciton, where the left side refers to the positive polaron and the right side refers to the triplet exciton.
Time-dependent charge distribution of the collision between the positive polaron and triplet exciton under an external field .
Time-dependent electron populations in the state of the polaron and in and of the triplet exciton once the positive polaron is injected into an APL.
A device of PLEDs used to improve its efficiency of electroluminescence. In the HIL, the spin polarization of the positive polaron is determined by the magnetic field . The magnetic field fixes the spin direction of the triplet exciton in the APL.
