Abstract
We propose a new theoretical approach to obtain the nanoscale morphology of rough surfaces from low-temperature adsorption experiments. Our method is based on one of the most realistic models of rough surfaces formulated in terms of random correlated processes. In our study the adsorption on the rough surfaces is theoretically described by random surface density functional theory (RS-DFT), which allows to take into account both the roughness in the normal direction and the correlation length of the lateral surface. Varying geometrical parameters of RS-DFT we fit the experimental data in the low pressure range, where the influence of the surface geometry is the most crucial. From this procedure we obtained best-fit detailed geometry of rough surfaces, which provides full information for further atomistic modeling. Also developed approach allows the calculation of the surface fractal dimension from the experimental isotherms. It demonstrates that the surface fractal dimension observed in many experiments is...
