Abstract

In this work we investigate the influence of adsorption-desorption noise on nanoresonators with random rough surfaces. Indeed, surface roughening leads to an increased number of adsorption sites and thus to an increased limit to mass sensitivity and decreased dynamic range leading to increased nonlinear behavior. Extensive analysis of the surface morphology is necessary because it is not only the roughness amplitude w that contributes to adsorption-desorption noise but also the lateral roughness correlation length xi, and the roughness exponent H that characterizes short wavelength roughness (<xi). The latter is shown to have a comparable effect on adsorption-desorption noise as the roughness ratio w/xi.
