Direct in situ determination of the polarization dependence of physisorption on ferroelectric surfaces
The electric polarization of dipoles on the surface of a ferroelectric material can influence the energetics of materials adsorption. The demonstration of this effect on the physisorption kinetics of gases such as carbon dioxide may be used to control adsorption and surface chemistry on the nanoscale.
