Lippmann-Young model in the study of optically active materials

The fotonic energy affects the contact angle of water on optical active materials:This effect, easy to determine, was recently analyzed in both diamond films and amorphous and crystaline silicon [1, 3]. The effect of wavelength on water contact angles is explained here on the basis of the Lippmann-Young ecuations. The type, p, or n, of each material surface was also determined as a function of the species present on each material surface. The Lippmann-Young equations are the basis of a useful and simple model for the study of the electronic behavior of optical active materials.
