摘要

我们考虑了一种基于集成了天线的石墨烯弹道整流器的太赫兹探测器。在室温下，该器件在70-440 GHz范围内具有数百V/W的外部响应性，并且没有截止频率高达0.44 THz的迹象。由于其零阈值电压和高饱和电流，该器件在超过3个数量级的输入功率下也表现出线性响应。

Millimeter and submillimeter range detector based on graphene ballistic rectifiers

We consider a terahertz detector based on a graphene ballistic rectifier integrated with an antenna. The device demonstrates an extrinsic responsivity of hundreds of V/W in the range 70–440 GHz at room temperature with no indications of a cut-off frequency up to 0.44 THz. The device also demonstrates linear response for more than 3 orders of magnitude of power input due to its zero threshold voltage and its high saturation current.
