随机粗糙表面纳米谐振器的质量灵敏度极限（由内源和与周围气体的相互作用引起）
Limit to mass sensitivity of nanoresonators with random rough surfaces due to intrinsic sources and interactions with the surrounding gas
摘要：
我们初步研究了热机械和动量交换噪声对具有随机粗糙表面的纳米谐振器的质量灵敏度极限的影响，其特征在于粗糙度幅度，相关长度和粗糙度指数H。事实上，如果与热机械噪声相关联的品质因数大于由于动量交换噪声而引起的品质因子，则对质量灵敏度的限制随着粗糙度的增加而增加（减小H和/或增加比率粗糙度幅度/相关长度）。最后，吸附-解吸噪声的影响，这也是由表面形态的影响，被证明在其他两个噪声源的存在下发挥最小的作用。
英文摘要：
We investigate initially the influence of thermomechanical and momentum exchange noise on the limit to mass sensitivity of nanoresonators with random rough surfaces, which are characterized by the roughness amplitude, the correlation length, and the roughness exponent H. In fact, the limit to mass sensitivity increases with increasing roughness (decreasing H and/or increasing ratio roughness amplitude/correlation length) if the quality factor associated with thermomechanical noise is larger than that due to momentum exchange noise. Finally, the influence of adsorption-desorption noise, which is also influenced by the surface morphology, is shown to play minimal role in presence of the other two noise sources.
