我们报告了一种基于光热电效应的碳纳米管（CNT）太赫兹（THz）探测器。我们实现了室温太赫兹检测，发现碳纳米管的光热电效应作为太赫兹检测信号，强烈依赖于电极金属，揭示了碳纳米管和电极之间界面处发生太赫兹响应的详细机制。这一结果为太赫兹成像的实际应用提供了强大的可能性。
We report on a carbon nanotubes (CNTs) terahertz (THz) detector based on photothermoelectric effect. We achieved room temperature THz detection, and found that photothermoelectric effect of CNTs, as a THz detected signal, strongly depended on electrode metals, revealing a detailed mechanism of THz responses occurring at the interface between CNTs and electrodes. This result provides a strong possibility for practical use of THz imaging.
