基于二维材料的机械谐振器的太赫兹探测

Terahertz detection using mechanical resonators based on 2D materials

Juha Hassel, Mika Oksanen, Teemu Elo, Heikki Seppä, Pertti J. Hakonen

摘要:

我们已经研究了太赫兹检测方案的基础上混合的电信号在一个电压依赖的电容制成的悬浮石墨烯。我们已经分析了相干和非相干检测制度,并比较其性能与最先进的状态。使用高振幅本机振荡器,我们预计在相干模式的量子有限检测的潜力。灵敏度源于原子级薄石墨烯或石墨烯相关2D材料的非凡机械和电学特性。

英文摘要:

We have investigated a THz detection scheme based on mixing of electrical signals in a voltage-dependent capacitance made out of suspended graphene. We have analyzed both coherent and incoherent detection regimes and compared their performance with the state of the art. Using a high-amplitude local oscillator, we anticipate potential for quantum limited detection in the coherent mode. The sensitivity stems from the extraordinary mechanical and electrical properties of atomically thin graphene or graphene-related 2D materials.
