What do you mean by the 'nature' of the surface?
Do you mean the elemental composition, the conducting/semiconducting/insulating nature of the material, the effect of adsorbed layers on the surface?

Look at the penetration depth of the frequency of the light being used in such experiments. Keep in mind that the standard photoelectric effect phenomenon is done using UV light, and on metallic surfaces.
