论文摘要
我们根据热载流子光效应效果评估波导集成的等离子石墨烯光电探测器，其性能以高反应性，数百AW-1的尺度和100 s GHz的尺度高的尺度同时表征。绩效评估基于辐射效应理论，该理论源自石墨烯的非核心。结果与最先进的等离子隆仪光电探测器相比，预测响应性的数量级高达两个数量级，同时将速度保持在同一水平上，这是由石墨烯中的电子静态散射时间定义的。
We appraise a waveguide-integrated plasmonic graphene photodetector based on the hot carrier photo-bolometric effect, with performance characterized simultaneously by high responsivity, on the scale of hundreds of AW-1, and high speed on the scale of 100s of GHz. Performance evaluation is based on a theory of bolometric effect originating from the band nonparabolicity of graphene. Results compare favorably with the state-of-the-art plasmonic bolometric photodetectors, predicting up to two orders of magnitude increase in a responsivity while keeping speed on the same level, defined by the electron-lattice scattering time in graphene.
