论文摘要
我们研究了亚克尔文温度下的电荷中性表二烯的基本电荷和热传输性能，在温度超过二十年的时间内显示了电导率几乎对数的依赖性。使用石墨烯的板电导作为原位温度计，我们在MK温度下介绍了电子 - 音波热传输的测量，并表明它遵守清洁二维导体的$ t^4 $依赖性特征。基于我们的测量，我们预测$ \ sim 10^{ - 22}〜{\ rm W}/\ sqrt {\ rm hz} $在可实现的温度低端的epigraphene bologe的噪声等效功率。
We investigate the basic charge and heat transport properties of charge neutral epigraphene at sub-kelvin temperatures, demonstrating nearly logarithmic dependence of electrical conductivity over more than two decades in temperature. Using graphene's sheet conductance as in-situ thermometer, we present a measurement of electron-phonon heat transport at mK temperatures and show that it obeys the $T^4$ dependence characteristic for clean two-dimensional conductor. Based on our measurement we predict the noise-equivalent power of $\sim 10^{-22}~{\rm W}/\sqrt{\rm Hz}$ of epigraphene bolometer at the low end of achievable temperatures.
