摘要

利用时间分辨太赫兹光谱研究了量子点敏化ZnO纳米线中电荷的产生、注入和复合。在注入时间内，不同代表性泵浦-探针延迟的迁移率谱表现出相似的行为，表明纳米线结构上存在自由电荷。

Charge carrier dynamics of quantum dot-sensitized ZnO nanowires probed by time resolved terahertz spectroscopy

Charge generation, injection and recombination in quantum dot-sensitized ZnO nanowires was probed using time resolved terahertz spectroscopy. The mobility spectrum at different representative pump-probe delays showed similar behavior during the injection time indicating free charges on the nanowire structures.
