摘要

电极是光电探测器(PD)与外部测量电路之间的桥梁。电极与敏感材料之间的界面电特性将主导光诱导电荷载流子的分离和收集,这被认为是影响光检测性能的关键因素之一。本文总结了紫外光分光器件中使用的电极材料,并根据其成分进行了分类。然后,讨论了电极配置(如接触类型、带状结构和电极结构)对紫外光分光器件光电性能的影响。还介绍了各种特定电极,如透明电极、柔性电极和生物电极。最后,介绍了紫外光分光器件中电极的前景,为其未来发展提供了指导。

Electrode materials and structures in UV photodetectors
Electrodes can be recognized as the bridges between photodetectors (PDs) and outer measurement circuits. The interfacial electric properties between electrodes and sensitive materials would dominate the separation and collection of photo-induced charge carrier, which are recognized as one of the critical factors influencing the photo-detecting performance. In this paper, the electrode materials used in UV PDs are summarized and categorized according to their components. Then, the effects of electrode configurations (such as the contact types, band structure, and electrode structure) on the photoelectric performances of UV PDs are discussed. Varied kinds of specific electrodes such as transparent electrodes, flexible electrodes, and bio-originated electrodes are described. Finally, the perspective of electrodes in UV PDs is presented, which provides guidance for their future development.

期刊介绍: Applied Physics Reviews (APR) is a journal featuring articles on critical topics in experimental or theoretical research in applied physics and applications of physics to other scientific and engineering branches. The publication includes two main types of articles: Original Research: These articles report on high-quality, novel research studies that are of significant interest to the applied physics community. Reviews: Review articles in APR can either be authoritative and comprehensive assessments of established areas of applied physics or short, timely reviews of recent advances in established fields or emerging areas of applied physics.
