项目摘要

Within the funding period, we have conducted research to further optimize our organic differential photodetectors, based on a metal/insulator/insulator/metal structure, for intended use in optical communications networks. Specifically, we have focused on the organic semiconductor layer which acts to absorb light signals and convert them to electrical signals via capacitive charging/discharging of the insulator layer. Using metal naphthalocyanines as representative near infrared absorbing semiconducting chromophores, we have applied and developed the techniques of molecular templating and solvent vapour annealing to control the crystallinity and crystalline orientation of the semiconductor thin films. Through such techniques we have improved the photodetector device figures of merit (detectivity and bandwidth) due to improved electronic communication through the semiconductor thin film. This work is currently being written up to be submitted to a peer-reviewed journal in the near future.

在资助期内，我们进行了研究，以进一步优化基于金属/绝缘体/绝缘体/金属结构的有机差分光电探测器，用于光通信网络。具体地，我们已经集中在有机半导体层上，该有机半导体层用于吸收光信号并通过绝缘体层的电容性充电/放电将它们转换为电信号。以金属萘菁为代表的近红外吸收半导体发色团，我们应用并发展了分子模板和溶剂蒸气退火技术来控制半导体薄膜的结晶度和晶向。通过这样的技术，由于通过半导体薄膜改善了电子通信，我们已经改善了光电检测器器件的品质因数（检测率和带宽）。这项工作目前正在撰写中，将在不久的将来提交给同行评审期刊。
