Abstract

Localized surface plasmon resonance (LSPR) is an intriguing phenomenon that can break diffraction limitations and exhibit excellent light-confinement abilities, making it an attractive strategy for enhancing the light absorption capabilities of photodetectors. However, the complex mechanism behind this enhancement is still plaguing researchers, especially for hot-electron injection process, which inhibits further optimization and development. A clear guideline for basic physical model, enhancement mechanism, material selection and architectural design for LSPR photodetector are still required. This review firstly describes the mainstream understanding of fundamental physical modes of LSPR and related enhancement mechanism for LSPR photodetectors. Then, the universal strategies for tuning the LSPR frequency are introduced. Besides, the state-of-the-art progress in the development of LSPR photodetectors is briefly summarized. Finally, we highlight the remaining challenges and issues needed to be resolved in the future research.

局部表面等离子体共振增强型光电探测器：物理模型、增强机制和应用

局部表面等离子体共振（LSPR）是一种引人入胜的现象，它可以打破衍射限制，表现出卓越的光聚合能力，是增强光电探测器光吸收能力的一种极具吸引力的策略。然而，这种增强功能背后的复杂机制仍然困扰着研究人员，尤其是热电子注入过程，这阻碍了进一步的优化和开发。LSPR 光电探测器的基本物理模型、增强机制、材料选择和结构设计仍需要一个明确的指导原则。本综述首先介绍了对 LSPR 基本物理模式和 LSPR 光电探测器相关增强机制的主流认识。然后，介绍了调谐 LSPR 频率的通用策略。此外，还简要总结了 LSPR 光电探测器开发的最新进展。最后，我们强调了未来研究中仍需解决的挑战和问题。
