摘要
We demonstrate that air-treated conjugated polymer diodes under photoexcitation give rise to a transient current exceeding a steady-state photocurrent by electron-spin resonance (ESR). The current induced by ESR is shown to exhibit a spiked time response for modulation of the resonance condition. The nature of the spike current is demonstrated to be a displacement current, which suggests that the spin transitions can change the film permittivity. This system has applications as devices enabling direct control of diode current by spin manipulation.
