Abstract

The extraordinary electronic and two-dimensional materials make them promising candidates to replace traditional photodetectors in infrared and terahertz spectral ranges. This paper reviews the latest achievements in graphene detectors in competition with traditional commercially dominated ones in different applications. It is shown that the performance of graphene-based infrared and terahertz detectors is lower in comparison with those detectors existing on the global market. The high sensitivity of hybrid photodetectors does not coincide with a fast response time, which limits real detector functions. The most effective single graphene detectors operated at room temperature are terahertz detectors, which utilize plasma rectification phenomena in field effect transistors. The challenges facing the development of focal-plane arrays in the future are also considered. Special attention is directed toward the main trends in the development of arrays in the near future—an increase in the pixel count to above 108 pixels, with pixel size decreasing to about 5 μm for both cooled and uncooled long-wavelength infrared arrays. To date, these questions have not been considered in literature devoted to graphene-based infrared and terahertz detectors.

红外和太赫兹探测器系列中的石墨烯基材料:教程

这种非凡的电子和二维材料使其有望在红外和太赫兹光谱范围内取代传统的光电探测器。本文综述了石墨烯探测器在不同应用中与传统商业主导探测器竞争的最新成就。研究表明，与全球市场上现有的探测器相比，基于石墨烯的红外和太赫兹探测器的性能较低。混合光电探测器的高灵敏度与快速响应时间不一致，这限制了实际探测器的功能。在室温下运行的最有效的单个石墨烯探测器是太赫兹探测器，它利用场效应晶体管中的等离子体整流现象。还考虑了焦平面阵列未来发展面临的挑战。特别关注的是在不久的将来阵列发展的主要趋势——像素数量增加到108个像素以上，冷却和非冷却的长波红外阵列的像素大小都会减少到5μm左右。到目前为止，这些问题还没有在专门研究石墨烯基红外和太赫兹探测器的文献中得到考虑。
