红外和太赫兹具有非常广阔的应用前景, 在光谱学、成像、无线通信和遥感等领域发挥着越来越重要的作用。但是, 由于红外、太赫兹波段的光子能量低, 相关的探测遇到很大困难, 所以实现高灵敏、高速和高稳定性的红外太赫兹探测是一个具有挑战性的工作。二维材料由于其高迁移率、带隙可调和表面悬挂键少等特点为红外太赫兹探测提供了新的机遇。基于光热载流子调控的二维材料红外、太赫兹探测器的发展方兴未艾。文中主要介绍了目前基于光热载流子调控的红外、太赫兹探测器的最新研究进展, 将从材料、器件结构、响应波段和响应机理等方面展开。

Due to myriad applications, infrared and terahertz are playing an important role in the fields of spectroscopy, imaging, wireless communication and remote sensing. However, be limited by the low photon energy in the infrared terahertz band, the detection encounters great difficulties, so it is a anenormous challenge to realize infrared and terahertz detection with high sensitivity, high speed and high stability. Two-dimensional materials offer new opportunities for infrared and terahertz detection due to their high mobility, adjustable band gap, and few surface dangling bonds. The development of two-dimensional material infrared and terahertz detectors regulated by photo-hot carrier is in the ascendant. This paper mainly introduced the latest research progress of infrared and terahertz detectors based on photo-hot carrier regulation. This article will expand on materials, device structures, response bands, and response mechanisms.
