Studies of long-lived photogenerated carriers in low band gap polymer photodiodes
摘要：
基于低能带隙聚合物的光电探测器中的缺陷在决定与通信波长相关的近红外光谱区域中的开关特性方面起着关键作用。详细研究了不同入射波长下长寿命瞬态光电流的带宽限制因子与温度、光脉冲宽度、偏压的关系。结果表明，光生载流子的主要输运机制在低温下受复合限制，在高温下受脱陷限制。观察到的带尾区域的光生载流子的响应较慢的一般趋势。
英文摘要：
Defects in low-bandgap polymer based photodetectors play a critical role in determining switching characteristics in the near infra-red spectral-regime relevant to communication wavelength. We carry out detailed studies of the bandwidth limiting factors of the long-live transient photocurrent at different incident wavelength as a function of temperature, light pulse width, bias voltage. The results indicate that dominant transport mechanism of the photogenerated carriers is limited by recombination at low temperature and detrapping rate at high temperature. A general trend of a slower response of photocarriers originating from the band-tail region is observed.
