Description
Surface roughness is an essential factor determining many surface phenomena, including adhesion, friction, wave reflection, microfluidics, electrochemistry, and wettability. It is conveniently described in terms of power spectral density of 2D height profile of the surface. I will discuss the power spectral density of particle monolayers widely used as sensors, substrates, catalysts, and antireflective or antimicrobial surfaces. I will demonstrate a close analogy between the surface power-spectral-density and the well known intensity of radiation scattering. I will also give a simple example of application of the function in characterizing particle monolayers
