透射半导体光学中热载流子驱动的噪声
Thermal charge carrier driven noise in transmissive semiconductor optics
摘要：
几种噪声源限制了当前引力波探测器的灵敏度。目前，主要的噪声源包括量子噪声和热布朗噪声，但未来的探测器也将受到其他热噪声通道的限制。本文研究了半导体材料中由空间载流子密度变化引起的热噪声源。我们提供了一个分析模型的屏蔽效应的存在下，载流子波动的理解，并表明，载流子噪声将不会是一个限制噪声源的第三代引力波探测器。
英文摘要：
Several sources of noise limit the sensitivity of current gravitational wave detectors. Currently, dominant noise sources include quantum noise and thermal Brownian noise, but future detectors will also be limited by other thermal noise channels. In this paper we study a thermal noise source which is caused by spatial charge carrier density variations in semiconductor materials. We provide an analytical model for the understanding of charge carrier fluctuations under the presence of screening effects and show that charge carrier noise will not be a limiting noise source for third generation gravitational wave detectors.
