英文摘要 | We present a theory of photocurrent spectra for a light-emitting diode fabricated by a π -conjugated polymer system. The tunneling through a barrier induced by the DC field dominates the dissociation of excitor states (i.e., photoionization of vibronic states) below the threshold. The spectra thus obtained explain most of the experimental results and also allows us to more easily position the S �� state and other higher states in the conjugated polymer. |
